About
Juan had it all— a vibrant world, a best friend named Greg, and an adventure waiting to unfold. But after a fateful encounter with a grumpy Dinosaur, he’s been cast down into the prototype version of his own game! Now trapped in a 1-bit world of unfinished code and forgotten assets, Juan must fight, platform, and puzzle his way back to where he belongs.
Switch between two distinct art styles—gritty 1-bit and polished 16-bit—as you uncover the secrets of the Prototype Realm. Use your whip, shield, and quick reflexes to survive enemy encounters, traverse treacherous environments, and collect the keys needed to escape this digital purgatory.
Can Juan reclaim his adventure, or is he doomed to remain a half-finished idea?
NOTE: Optimized for Steam Deck — runs smoothly at 60 FPS with default Proton settings.

Prototype Juan is a fast paced, side scrolling action platformer that blends old school challenge with clever modern design. The first thing you'll notice is the smooth transition from 1 bit to 16 bit worlds. A creative touch that gives the game both style and substance. It's a unique visual experience that feels like stepping through different eras of gaming in real time. For a 1 man project, the attention to detail is impressive. Small design choices, for example, highlighting the keys you've already collected, show the developer understands how to respect the player's time while still maintaining a sense of challenge and exploration. It's a thoughtful feature that keeps you focused on progressing rather than backtracking unnecessarily. Prototype Juan carries shades of classic games like Zelda, Mario, Ninja Gaiden, The Impossible Game, Castlevania and more! Each influence can be felt in its own way, the precision jumps, tight combat timing, trial and error rhythm all combine to create something that feels both nostalgic and new. The gameplay itself is tough but fair. It demands patience, quick reflexes and a willingness to learn from mistakes. You'll die plenty but it never feels cheap. Each attempt pushes you to improve. After beating the game you find yourself wanting more and you get more! There is quite a bit of bonus content you unlock that the developer put thought and time in. The dialogue and in game text also add personality with bits of humor sprinkled throughout real gamers will understand. Overall, Prototype Juan is a standout experience, challenging, stylish and full of heart. It's a must play for fans of retro inspired action games who appreciate a smart mix of difficulty, charm and creaticity.
Haven't had this much fun on a platformer since Celeste! BUY. THE. GAME!
Very short, about 1 hour to finish the main game. Decent little platformer, somewhat similar to games like [b]Daddish[/b] or [b]100 Pumpkins 2[/b] (which are also really short). [b]8-Bit Boy[/b] is another game that springs to mind too (though that one is a bit longer). The music was exceptional and the controls and overall design was good. This game shows the devs potential, should they decide to try and make something bigger and better. Perhaps if they did do that, the result could be something like the excellent retro platformer; [b]Fallen Leaf[/b]. Perhaps that's a stretch, but they've certainly demonstrated their competence and potential with this release.
Cute as hell artstyle, tight platforming. Greg suxs
Very cool game. The music throughout is charming, but i want to highlight the music that plays throughout the prototype areas: it is awesome. Can't go wrong for the price. I'm under the impression it's a one man dev team. Regardless, I am getting my enjoyment out of this and will see it to completion. This is a speed runner's game. When I looked at the top and saw how many lives i had, and that there was a timer, i was like, "oh ♥♥♥♥." I do not play games like this. But this is pretty dope. Random thought: I wished death resets were a bit quicker at first, then I came to appreciate the moment it forced me to relax for an extra second. YMMV: Controls feel a bit slippery to me, but I can't tell if that is typical of this type of platformer or not. It feels like it is built for speeding through and not stopping, which I am just not skilled enough to do. A handful of areas have slapped me down to the tune of 20 or so lives, but you end up earning more back from coins I believe (x5 at a time woot!). Stepping too close to a spike and dying as I am setting up to start a sequence had me cracking up. ♥♥♥♥♥♥♥♥ spiders. ♥♥♥♥♥♥♥♥ spikes. You need to be precise. It's fun. Highly recommended.
This is my platformer game of the month! :) Very fair.
Juan heck of a game. Jumps smooth, Jokes smoother.
Im not normally a fan of platformers, but this one is a lot of fun. An absolute blast! Do yourself a favor and pick this one up
Wonderful 1bit pixel art style, with great jokes, tight platforming, forgiving checkpoints, and fun writing. If you’re a fan of Celeste or Holoknight but you suck at them (like me) pick this one up and give it a shot. A fun short play that I’m going to run through at least two more times.
Very tight platformer. Excellent music and a lot of fun. Greg does indeed fart too much.
