Oh wow, the music is an absolute banger. One of the best tracks I've heard through the entire Jam. The music basically got me half-dancing during the entire duration of the game. it felt so good together with the aesthetics, the art fit the music very well as well.
The gameplay was quick and responsive, as it should've been. The only bug I've encountered have been a bit of buggy physics (especially in level 4, got the bullet to just straight bounce back to me and kill me :p) but except for that, a really good entry. ^^
