And also, when more games are put into this project there should be a play all button, so it counts your total score up, also maybe setting up Kong's High Score API.
Maybe extending the game canvas would help. Also, I reckon you should get a custom cursor in there.
onClipEvent (mouseMove)
{
_x = _root._xmouse;
_y = _root._ymouse;
}
onClipEvent (load)
{
Mouse.hide();
}
Suggestions:
Fast Forward button (maybe)
Upgradable towers
More levels maybe?
Well done CuaticGames, a very good game you have made and I hope to see a sequel, + if you agree
