Ok so first of all, you should not present your game by calling it crappy or buggy (even if it is it can spoil the first impression, you know), we've all been here, 3d games are, at least in my opinion, harder to make and polish than 2d games. So, about the game: 3d platformer is a cool idea, i think there are no troubles with level design here. Yes, the controls can be weird sometimes but thats alright:). I loved the fact that the collectibles that are used to complete a level give you random abilities, thats actually a really cool idea. This way player has to make desicions based on luck, which sometimes is kinda not friendly. It took me some time to figure out how Wall climbing works, but now that i understand, it feels really satisfying! I liked the "death" and "next level" screens, the pitch+slow filter on music is a good decision. One thing that is not ok i think is lost progress, after completing the first level and dying on the second i need to replay the first one again, maybe a checkpoint of some kind, or a menu with level selection will help. Also I liked the camera "'iveliness", the way it wiggles around makes it alive you know. Overall, really good idea and the emplementation is nice, keep up the good work and do not belittle yourself and your work, everyone has a chance in these jams!:)
