WOW amazing, basically a finished game. just a lil more polish and good to go! really nice concept, aesthetics and music are great too, feels very retro
i just wish the player got rewarded with mana (or whatever that is) for hitting the enemies with the right color,
would be cool if every wave consisted of enemies of at least two different colors, so you wouldn't have to hit them knowing you have no damage, just to change colors.
