I think there might have been some issues with the mouse not being locked, as I found I couldn't turn the camera fully round, and it got constrained to an odd angle. I also ended up getting soft-locked on level geometry in a few spots, past the initial tutorial section.
I'm a sucker for platformers, and this certainly is a rage game of a platformer - which given the level design seems intentional. I'm not a huge fan of those kinds of games, but for what it's trying to do, it succeeds.
Visually it's simple enough - but I feel like this could really benefit from some polish to smooth a few of those rough edges down.
Given it was made in half a day though - not bad at all. It could probably do well with the right polish and refinement to the core game loop.
