Very nice game, but a little basic. Some enemies seem to behave differently (vulnerable to different weapons), although there is no indication with color or shape. A minor bug: Once you click on a unit to build, you can't change your mind and "unselect" it anymore, forcing you to build that even though clicking it could have been a mistake.
Also it's a bit annoying that if you want to build the same unit type multiple times, you have to click on it every time again. Keyboard shortcuts 1-4 to select each unit to build would be great. Another shortcut for upgrading and selling, and the game would be a lot more usable and fun to play.
Hmm, the graphics part works smoothly for me, but it seems to be dropping input events. Attempting to upgrade a turret when there's a lot of action happening on screen requires clicking a bunch of times before it finally registers. (Chrome 9.0.572.0)
In Firefox it always reported >40 fps, however I could see that it was dropping massive amounts of frames, to the point where creeps would be coming in the entrance and then be halfway across the screen.
Amazing performance. If it had a button to manually trigger the waves instead of sending them off automatically (allowing me to rethink things more), my afternoon would be gone now.
Pretty cool - could definitely use some more work - but still well done. (Got a copy of the html from Google cache, and the javascript from the Gist posted in this thread.)
The targeting seems off. I expected the towers to attack the enemies furthest along the path, but it seems like they might be attacking enemies closest to them.

Still, quite addicting game! :-)
