Cool game! I had a lot of fun with this one. The whip felt really satisfying, the sound you picked was on point, and I found myself just kind of standing around whipping, which is always a good sign. I like the robot's design and animation, too.
I think I wound up cheesing the first boss by getting behind it, I'm not sure if that was intentional. If I'm looking for complaints the starting movement speed was a little slow, but overall this was a good time!
