Awesome visuals, nice sounds - Decent difficulty - I like how you sort of spice the game up by upgrading your monster. And the fact that it takes ages to upgrade it.
However, I do not know if I'm the only one who experiences this, But my game seems to 'bug' at certain times. This occurs randomly however the problem is that sometimes the new wave simply doesn't come?
The powerups do spawn, but the enemies does not.
Am I the only one with this problem?
It is sort of annoying..
Anyway, Thanks for a great and addictive game!
