I definitely see the binding of isaac inspiration here! Really great art-style and an interesting theme about the more "power-ups" you acquire the less strong you become :)
I don't know if the emotion (peace, happiness, anger) I chose actually affected gameplay but it would be nice if they were different. Also sometimes when you enter a "room" the monsters attack you straight away meaning you don't have enough time to dodge/attack back. Perhaps a 1-2 second delay when you enter "rooms" could easily fix this problem ^^
Overall, amazing job!
