love the game, but i feel like you should change the first boss. or just the confusion effect in general. it is always a bad idea to take that kind of controll from the player. 

for the first boss, once you get hit by the confusion effect once, he starts spawning in his minions, making it almost impossible not to get confused again

one way to fix this might be to increase the damage but make the confusion effect only last for something like 2 secconds. or you could remake the confusion effect completly, which i would prefer personally
