Great job. Especially in such a short amount of time. Love the look and the simple color scheme along with the menu and grid system. I didn't have a second player at the time. But I could see how this could destroy a keyboard! :-D
The graphics are fantastic! But I had a tough time understanding what to do and what the goal was. I didn't know how to make the instructions go away (turns out it was pressing Esc). I would've loved a tutorial for this game! Also, a Player vs. Bot mode would be great!
