Everything is amazingly polished, other than hitting an enemy, which felt pretty weird (to have everything like pickups kills and blanks be so polished and this just as important thing not)
I liked the art, it was very consistent and nice, you really knew what to focus on and what was happening.
I don't feel like the game had anything to do with confined space other than being a bullet-hell which is the requirement of the jam which was a bit of a bummer.
There were no sound effects which is a bit of a shame :(
The music was a banger and fit like a fiddle!
The leaderboard gave a pretty cool motive to replay the game, and the score was really nice to get.
I wish the difficulty spike was a bit less but other than that, awesome submission, amazing job!
