Really well made game, and probably the best art I've seen so far. My only complaints are:
1) I don't really like the hour of code-ish core gameplay, maybe adding more mechanics to spice it up would make it more interesting? It's not that the gameplay is bad, I just wish there were more mechanics to spice it up a bit. For example, what if there were bridges that had to be activated by switches, or elevators that would take the bots to different floors, or just something small to make things a little more interesting (more tiles?).
2) The sound effect when the robots crashed into each other was a little loud lol.
Other than that, the game was really well made. The art and the level of polish really stood out, so kudos to you for that! Good stuff!
