Would be great if the score was shown while playing, and I think the graphics really need some improvement to look smoother. just keep on working and this will turn out to be a really good TD. 3/5
seems like a good TD game and I really like TD games :) 3/5 so far must play some more, reminds me of some other TD game quite much with small soldiers, tanks etc.
Somekind of story would be good, different weapons to choose from, more and moving targets. At least 5 missions hopefully more, some better graphics and sounds (traffic, environmental..)
some dialogue. Much of this could really improve your game but it is a good start!
tournaments, multiplayer, differents types of paddels and super smash, combos and such and you´ll have a real winner hopefully with achievements. for now 3/5 because it is entertaining!
