At first, I thought this would be a basic tower defense game, where you simply place down 1 out of 3 towers and wait. This has upgrades, powers, mana, healers, and makes these 3 basic towers more than what they seem to be. 100/10
Can you perhaps add more races and hideouts? Maybe birds, who the cats could chase like dogs do to cats, have a chat for dogs that other dogs can understand, but not other races, and give us some color customization?
I tried 8,4,2 and thought it looked a bit like a head. :P
Now imma list all the ones I tried and thought looked cool, because I don't want fifty comments, all by me:
100,101,105 which I saw some jewish stars (I dunno the name of em) in.
1635,11,15
826,826,826 which makes a plain circle in the middle, and it's surrounded by pixels. Hope these were interestin! :3
