Ahh this is such a good entry!
From the graphics to the gameplay, very smooth stuff. I really liked the overall graphics, all the particles and lighting effects are great. I really wonder how you did that overall candy-colouring of the game though? Is that some kind of colour overlay? Really adds a lot to the visuals, I wouldnt mind knowing how its done. Ive added this game to my gamejam references list :D
The only thing I felt was lacking was sfx, which Im guessing you ran out of time for. And some kind of radar or indicator of where enemies are would have been handy, maybe some kind of red blur on the edges of the screen to fit in with the visuals and give you a vague indication of enemy positions. But perhaps without it, it makes it intentionally stressful ;)
