Wow! Just... wow. Fantastic game. It took me three hours to find all 26 bolts! It's a little rough around the edges, but this is a really solid and fun 3D platformer! It reminds me of early 3D platformers like Battle for Bikini Bottom and the Pac World games. Absolutely insane that you guys pulled this off in a two week game jam.
If I had any one complaint from a gameplay perspective, it's how difficult it was to pinpoint the last 4 or so bolts.
I'm hesitant to name specific bolts, but there were a few that were hidden enough that I kinda just had to stumble upon them after traversing an area 5 or 6 times... The world's big enough and complex enough that it would be nice if there was some sort of area separation or something. Kind of like the obelisks in "The Witness" which indicated collection progress within a general part of the map. Just a sign at the start of each of the three main areas indicating how many bolts are left would do. Or you could go the Nintendo route and have some sort of hotter or colder system (e.g. korok mask), but that feels like it helps too much if you ask me. I also think this problem is exacerbated by the camera being so close to first person. The player can see less of the world at once, so it is harder to find things hidden around corners and the like.
I really love the music, and they really fit each individual part of the game. However, I'm not sure changing the music based on which way the player is facing was a good idea... I think you were going for serene moments of quiet, and sometimes that worked, but sometimes it instead disengaged me from the game because the change from music to quiet and back to music again was too abrupt. This is a very hard thing to get right, especially in a 3d game with a lot of vertical movement, so kudos to you for trying! However, I also wanted to give my honest thoughts on the matter.
Sorry my criticisms are longer than my praises lol, I really do think this is the best and most ambitious game of the jam! Great job y'all, you should be proud.
