Yo! Nice game!
I like the aesthetic, with the brainy walls and the emotion enemies.
The gameplay could get some juicing up; hiting enemies could make some particles fly out of them, and while you're connecting and dominating an emotion having the enemy glow or have some particles fly out would be pretty cool.
Also - sometimes I enter a room and the enemies immediately jump on me, giving no room to dodge. I feel like that should be fixed, maybe the enemies won't attack for a second after you entered a room?
Eitherway, nice game! I enjoyed it.
