gameplay loop was really fun, nice work! there was also a lot of polish in the animations and effects, like the leaves flying by, that made the game feel really dynamic and alive.
i do wish the bugs were ironed out, though. they didnt end up being too much of an issue for me personally, but it's really important to deal with those gamebreaking bugs because they have the potential to completely halt the experience in a way that leaves the player with a bad final impression, especially if theyre not very understanding of how hard game dev is. i think it was nice that you set expectations with the opening text, but as others have said, it does move just a tad too slowly which can cause frustration, and when youre immediately mentioning that the game has game breaking bugs... that can leave a rough first impression on some people, which sucks because your gameplay is really good!
i think it may have ended up a bit better with a deliberately designed level layout, since im sure that procedural generation took up a LOT of time that could've been used to fix bugs. it's a game jam, after all, nobody's gonna be too harsh on your game for being short, so you may as well make it as tight and polished as possible imo! (and also, the jam leaders on the discord said you're allowed to do bug fixing if you note it in the game page info... do with that what you will)
its a cute, visually appealing infinite game with a simple control scheme and a clear goal, that's some incredible design work. not to mention that it actually incorporates the decay theme pretty well, which a LOT of games on here didnt even TRY to do! nice work all around, you've got some really strong design and coding skills!
