A nice little Bullet Hell Game. But The mechanics are kinda counter productive? Like why would you need to shoot down the colored shrimps if you can just dodge them instead to not cause bullet explosions. I do like mechanic with switching gura between red and blue gura. Even though it took me a bit to figure out what the difference is so maybe add into the tutorial that they can only hit and be hit by the opposite colors. For the colored shrimps a recommendation is either as the others said include a scoreboard so there is a usage in shooting them down OR making them nuisances if you DONT shoot them down. like shooting big sprays of bullets down which are hardly dodgable so you have a need to get rid of them. Otherwise I like the idea!
