Nice game was fun to play, I finaly understood how to beat the pentagons. At first I thought it was time based battle but apperently you need to hit them with their own munition.
Sad that the lost boss battle was easy to defeat himself with those long attacks. Super polished game, theme was in there and all the shapes to.
I also experienced a freezing in the gameplay, but that's probably because you haven't changed to a CPU particle emitter.
