I really like what you did with the art and the atmosphere! The bloom was really effective with your color choice of combining bright colors with generally darker tones. The movement was very responsive and I liked that double jumping reset your dash allowing you to get two dashes in the air if you spaced them out right. I think the game could be more exciting with complex enemies, such as enemies which shoot bullets at you for example. The movement is really tight so you could throw some difficult attacks at the player. Since the goal is finding and killing all enemies in a level, it also could help to have secret powerups to find in the level to help you win. Good work overall!
