WTF!? I was going to bump my rating from 4 to 5, because I just tried multiplayer and its awesome! BUT, after finishing with multiplayer, its lost all my completed scenarios!
Bomb options show up behind other bombs, making it hard to see. - Selecting by mouse over is really weird, why not just click them? - Stop the timer when the level finishes. - I finished a level, clicked replay, then quit without finishing the level again, and I could not skip past it from the menu, I still had to finish it. 3/5
Also, clicking in the grey background of the sidebar deselects the tower. This annoying when trying to upgrade and missing the button, thus having to select the tower again.
On the last wave, clicking next wave will increase the number, you can do it indefinitely. The heat ray tower is sometimes aiming in the wrong direction, but enemies still die. Make the text above enemies HP unselectable (use TextField.selectable) to prevent towers behind the text being unselectable while enemies are in front. Getting better, can't wait for the finished game.
