Great start for a concept... Think about bosses, power ups, some kind of replay value... And even more interesting -- multiplayer co-op and versus modes.
The little jokes are great, the concept is wonderful. The control isn't precise enough (as my past robots don't do exactly what I did the first time).
This leads to a 4.9/5
People arguing this is a good game, explain why? Graphics.... no, AI definitely not, a new concept not that either...
Oh massive body count and blood via clicking, nothing like blowing up hundreds of stick figures. I voted 1/5 even though it probably should get a 3/5 just because of all the people voting 5/5.
