a pause and a mute button would be nice.
yes the game gets more difficult withe time, but at the beginning it seems like the bubbles were lagging xD maybe you could do it more fluid.
and i miss there something ... that should make the game interesting
the spells are that strong, that you won't need to attack by normal mouse click. get the normal attack stronger / more usefull or the spells weaker. but anyway, nice game :)
nice game. the only think i dont like is that the enemyes drop the weapons to often and you pick them by accident if you rush into them. but this was the only think :)
