Welcome to Ludum Dare ^^ I like it, though I'd prefer a little more challenge. Grats on your first game though :D

Okay for a first try. Get involved in the community! And please, sound makes a game so much better.

I liked the fact that you made it get more difficult the longer you played, smart. Awesome for a first game! Sound would have made it fab! Welcome to LD48

Definitely a very good first game. The graphics look pretty good. Biggest comments would be about sounds/music (as people have said) and also maybe giving some cannons a cool-down. Right now I feel like the game is easy as long as you mash the mouse button right before one hits, and then becomes impossible when there are too many. Using the keyboard + cooldown might make it easier to control the difficulty (and turn the challenge into one of coordination). Overall good job, I definitely haven't played a game with this exact feel before.

I like it :)

227 points. It hooks you up nicely: I'll hold the next wave too! :)

It's a good first attempt. Second the need for sound and music. Also, I didn't like having to mindlessly, repeatedly click so much.
