That was it?
Well, it was an "ok" concept, but things when too simple, it's just that isn't it? TOO simple?
The whole point of the game is just to move around the mouse to pop balloons. . . but then you don't get anything in return (except for mild entertainment).
It's ok :-) But maybe to make it better, do SOMETHING when you level up; maybe weapons or something but really, I can't think of much but maybe to put more effects up (level up and the balloons pop with more sparkles or flares?)
Just keep going ;-)
