Really loved the simple graphics of this entry! Honestly the really simple linework with different colors really just did it for me! The shooting and dying also had really good feedback with the screen shake and particles, so well done on that! As for the theme, it was essentially just a sprite swap between hazards and powerups, so I don't think it really did anything interest with it there. But it is a solid, good looking game that is fun to play, so good job on that!
