Very cool atmosphere and art style, and a surprisingly large level for a game jam game!

A few minor issues that I encountered:

• The mouse sensitivity is very low on high-dpi displays when the mouse is captured.
• There’s no indication that smaller blocks can be picked up; maybe a sound cue when failing to pick up the larger block could work, to show that the key can do something to cubes?
• You can soft-lock yourself in the tutorial by clipping the box through the ground

The graphics are really nice and the concept is good!

Sick jam entry! Absolutely love the aesthetic going on in this one! The puzzles also seemed interesting up to the point I reached. I had gotten stuck for a bit at a section where you have to use a cube to jump a wide gap, but then a white wall blocked the path shortly after. I honestly am not sure what the intended solution there was, but it was while stuck there that I discovered this game has a sort of Portal-esque cube riding and... well the rest of the experience ended up being quite a bit sillier lol. Tragically, I wound up hardlocked to a Null pointer exception on a collision a couple rooms later, so I wasn't able to entirely complete the game, but nonetheless had a blast with this one! Great work from what I've seen in it, and stellar stuff with the rendering going on!

Cool game! I really like the graphical style :D

If I had one suggestion, it'd be to make the player movement a bit faster, especially in the long corridors. Though I suppose them being so long adds to the sense of "the void"
