For everyone asking about hotkeys, read the instructions. They clearly state, "Notes:
a) The absence of “Hot Keys” is on purpose; Hot Keys would ruin the current balancing of the battles"
I found a bug!
Fight the 3rd boss; Take him down, then enter Pause. The game should continue, and the boss will change into the final boss, and you'll be unable to continue, unless you enter then exit the shop.
You'll be forced to fight the last boss with the pause screen in your face.
Please fix this!
I enjoy the game, it's a very interesting concept...
But holy crap, that aiming system.
If you aren't going to zoom it in for us, give us a guide line of what angle the ball will go in. Holes such as #12 are EXTREMELY frustrating without it and pull away from the fun greatly.
