Even more fun then the way to make basic arrows fire constantly with no presses is doing the same thing with the other arrows when they are level 5. I have confirmed you can completely afk dragons, but the demons are a maybe.
So simple and addicting. I would say for the next game have more in game medels even if they don't get badges. They would make me replay again and again.
I gave it a 4 mostly because of how interesting the next one could be. There are some major problems that need fixing, but the game is well enough put together that the designer deserves to have his/her work recognized.
