About
Junkster is an all-new 3D action platforming adventure with a unique building mechanic.
When an intergalactic cargo ship crash-lands on a dangerous junkyard planet, it is up to a scrappy, little construction bot named UM-13, or UM for short, to save the day!
Armed only with his trusty robo-wrench, UM must transform the galaxy’s useless garbage into slightly more functional garbage as he searches for the parts to repair his ship and recovers his lost cargo of precious human artifacts.
With a visual style that captures the retro vibe of 80's era American comicbooks, each action-packed issue sees Um go toe-to-robot-toe with hungry trash mutants and renegade bots.
And as a special bonus, each exciting issue comes complete with a Junkster toy to add to your collection.

Junkster is a solid little game that, while it doesn't reinvent its genre, remains enjoyable to pick up and play. In many ways, it feels like an extension of the shrines from the last two Zelda games, focusing more on creativity and problem-solving than on reflexes. The building mechanic is well implemented and fits naturally into the progression. However, you'll often find yourself relying on the same pieces—usually the longest blocks—to create platforms, reach higher areas, or activate switches. The robot-building aspect is an interesting idea, but it's not used nearly enough. Some levels introduce a unique gimmick only to abandon it entirely in the next stage. This is one of the game's main shortcomings: the levels are fairly short and rarely combine the ideas introduced earlier. I would have liked to see more ambitious stages that gradually build upon previous mechanics to create more complex puzzles. Because of this, Junkster sometimes feels like a promising project that never fully realizes its potential. The few platforming sections don't add much to the experience and often feel more like an obstacle than a meaningful addition. The game's world is colorful and well crafted, with a cohesive visual style. The protagonist controls well, with the ability to attack, double jump, and glide. However, don't expect unlockable skills, weapons, or character customization. The only collectibles are a diorama and stickers. I completed the game with 100% completion in about eight hours without much effort. I would have liked a longer adventure with more variety, deeper customization, and a greater challenge. The game remains very easy from start to finish. More demanding puzzles involving different shapes to connect, fit together, and combine would have added a lot more depth. Despite these criticisms, I still recommend Junkster, mainly because of its very affordable price and its overall quality. It's a charming and relaxing experience that should appeal to players looking for a lighthearted puzzle game.
This is a nice 3D platforming game. There's some combat but it is pretty simple. The stages are pretty varied and fun. The building element is fun but in a couple stages got a little tedious. I felt like some puzzles could have been a little more clear about what needed to be done but most were well designed. The art style and graphics were very nice and I really liked collecting the "toys" at the end of each level. Overall I think it was a fun game and is priced really reasonably.
I've gotta say I am impressed to the point I feel the need to make a positive review. Every once and awhile you come across a game that you can tell someone put a lot of time and effort into just by the little added details, additional animations and sound effects that aren't required for the game to function, and just crafty ways the characters move and function. The game is really fleshed out and unique down to the smallest things. This is one of those games. Even the main menus done with their theme and complete, well made animations instead of just buttons is excellent. Little hidden gem at the time I write this definitely worth $10. I bought as an "Eh, this looks like fun and something I would enjoy since I like robots and building things." It's a perfect blend of building things to solve puzzles, platforming, and exploration as you try to find those last hidden collectables around the levels. It scratches the itch just right to where you want to go back into the levels to get the things you missed, or not finish the level until you 100% it the first time through. I've had a one or two instances where the current puzzle/obstacle in the level was a bit tough to figure out, but not unbearably so, then all of the sudden you get that "Oh jeez I know what the solution is." Not a super long game, but a well made game that is fun to play and will keep you entertained for a few afternoons definitely worth the price listed. My one and only 'complaint', would be in the level 'A Fridge Too Far', you have to get a piece from a robot flying in a circle overhead. I ended up looking up a video online of someone else playing it to figure out that you don't kill the robot or walk into the part he is carrying (which is how you collect other loose parts in the world). You have to use the 'deconstruct' button to take it from him and can do it from a small distance. This literally never occurred to me since you 'deconstruct' buildings and robots you build, but you smash/attack other parts in the world or enemies to free non-assembled parts and collect them. In other words, you have to treat this specific enemy like a building bolted to the ground, and not an actual enemy. However once you figure this out, it is simple enough and the same mechanic/method is used in later levels.
This is a fun, charming game that reminds me of 3D platformers I played on PS2 and Gamecube years ago. Though I've only played the game for about an hour as of this review, I've found the game to be fun, good to control, and fairly creative with its building puzzles. I especially enjoy trying to get the more hidden, out of the way collectibles, which is always a plus for me. I can recommend Junkster to anyone who enjoys a good 3D platformer, especially at such a low price.
Primer reseña en español, me recuerda a los juegos de Lego y de Crash Bandicoot. Esta muy bueno
just early in the game but i was quite happy with the balance between the buildings and the actions, you dont have to be very creative to complete the mission, just have to figure out a way and make it work. The UI and art shine in this game, they are very consistent and work to gether well to make all things like a comic book, for this price i was really surprised this game have such a quality.
Awesome little puzzle platformer! Took me about 8 hours to 100% but could probably be done in about 6 if you're not doing anything else at the same time!
I know I only played this game a little bit but I can already tell it's great. If the review is up I didn't change my mind.
Not bad! Feels like playing something from the PS2/Wii era, in a way that tickles the nostalgia. I think the core controls feel good, and the building is largely brisk and intuitive. Level variety is also reasonably strong, and visual variety is, too. In general, Junkster's production values and length are higher than one would expect for the low pricetag, but the low confidence is explained by other things - the combat is *extremely shallow* and the puzzle-platforming is not terribly deep, either. I'd also note that while the collectibles probably did successfully extract another 1-2 hours of playtime out of me, I'm not sure the tradeoff was worth it; toward the end, I felt the game losing steam and just wanted to be done with it, and I may not have felt that if I'd just played with a faster pace to begin with. The sound design is very punchy, but its extremely "modern-game" style of boomy, chunky sounds borders on cloying. Again - it's not bad, I think it meets the expectations set by its trailer and screenshots. Nothing really wowed me, but it feels nice in the hands, and it's unique enough to be worth the time.
Peak visual style and aesthetic choices all the way around. All the basic mechanics are very solid, I wish some of the puzzles were expanded on further -- it almost feels like a solid proof of concept. I gotta sing it praises even if it's a bit short cuz at its asking price, the basic experience over-delivers. The main downside: There's a few and far-between larger enemies to fight which do leave a lot to be desired. It can't be excused by the simplicity of the combat, either, the enemy design and behavior just weren't quite IT for those larger enemies.
