Really fun game! I love the idea of giving bonus points for matching the correct color. It makes gameplay more interesting and gets really chaotic when other colored portals start popping up.
The power-ups and debuffs are also a great idea. They make the game more fun and force you to think a lot more while playing.
Sound and music fit really nicely too, they make the game feel much more alive.
Overall very good game. Nicely done!
