Hey there! Am glad you liked the game! about the harmony, you are supposed to discover combos that work together. so bagpipe and drum dont work together, but bagpipe and lute work together. so thats why when you make wrong combos, it sounds bad. also there actually is a health bar under the player and enemy, I guess you didnt notice that lol. Finally, I agree with you. The game feels a bit slow, but we didnt have time to polish and make it more fun so, yea.
