Love the retro vibe and atmosphere and the characters are hilarious 10/10
Cool game! Really nailed that old style. The story was fun, I like all the little interactive segments. Its got a great atmosphere, the art's quite nice! There's some neat stuff in here, it's definitely worth the price. At only a couple hours long (perhaps a bit longer if you go achievement hunting) it doesn't ask for too much of your time and it doesn't bloat itself with unecessary segments just to extend its run time. So, very neat! Pick it up if it looks like your thing, better yet check out the demo for the first chapter. I don't think you'll be disappointed.
it's fine. weird that there doesnt appear to be the modern point and click staple of hold tab or some button to highlight all interactables. definitely took me longer in some sections cause I didnt realize I could click certain things. also 1 section, I have no idea how I got to a certain area, but I was wandering around forever just to find a computer chip. overall enjoyed it, real weird
this kicks ass. good bite-sized adventure game that I never really got stumped on. The puzzles make their own weird sense and it all just flows very well.
Fun little game inspired by old school 90s era point and clicks. Its also got a really quirky and somewhat ominous atmosphere and vibe that I enjoyed. The only downside is that some of the puzzles towards the end can be pretty obtuse and frustrating, and there also seem to be no real checkpoints within the chapters, so if you have to quit out of one of them you'll likely need to replay it from the beginning. Thankfully they're short so that doesn't take too long. Overall it was well worth the fiver.
great game to kill a few hours! great soundtrack, funny characters, and nice atmosphere
A good game that's faithful to what it strives to be. A bit shorter than expected, but the time itself I spent in it was a pleasant experience. Extra point for making me think the chest puzzle was a more intricate puzzle than it actually was; it made me laugh out loud when I found out what the actual way to solve it was. 9/10
I had such a fun time with this game! The characters were a blast, the puzzles had that old game feel to them in the best way, and I love the different endings. Great game!
sludge <3 cute and short, puzzles are fairly simple graphics and story are charming demo (~15min) was representative of full game (~2hr)
Such a nice game! everything from the artstyle and the soundtrack, to the funny moments just makes this game so worth playing :D I know that there has been put so much effort into it, and you can really feel that! I can't wait to continue with more playthoughts and see what other secrets i might find! <3
