Good game
Like the concept. Beating down on everyone for a lottery ticket is always a nice premise. But similar to what was said before, upgrades would help in this. I don't necessarily need a way to move because of the game engine but maybe other characters have ranged weapons instead of a staff. I remember Goku from the old legendary "Journey to the West" tales. Why not have the others as PCs with a different strategy?
Other than that, the last boss was difficult to beat. Let's see what happens for the next game.
