Rebolutionary spinning robot technology!
Very interesting mechanic of one button movement, very quirky enemies and lovely art!
Since you have the mechanic and the world all done, I would be interested in seeing
"Rebolution+: the spikes and lazers edition" where you use the same gravity mechanic to squash these pesky bug-animals. They still cruise around, but instead of avoiding them, you try to hunt them.
Well done!
