So the game is pretty good in general, but there is definetely NO infinite playing potential that some other Idle Games have.
The "End Boss" is somewhat challenging to defeat (I abused cancelling the boss's attacks with either Catapult or the Heal).
Bugs here and there, sometimes you attack your own shield in Defense and heal the enemies, but after the shield was down that stopped (at least for me).
