The art is so nice, and the music is well implemented, together they create a sort of Binding-of-Isaac type feel that I really like!
I didn't ever figure out what the letter buttons do? Should I be playing with a controller? It'd be better to make that more obvious.
I've seen a few other games in this jam about specific movement controls breaking, but this one stands out from them by actually showing the controls on the player, and the genius screen wrapping that stops the player from getting stuck. Good job!
