I really like the aesthetic, but it's a little funky moving someone restricted in rotation to a 2D plane around a 3D space. The concept is fairly solid, but I couldn't tell if I was getting oil from enemies or not. Also, is there anywhere to go, or is it just the square arena? I wasn't sure if I was supposed to be progressing anywhere or just surviving for as long as I could.

At any rate, which some polish, the game could stand out with its unique aesthetic. It would be nice to add some objective or more complex space to move through. Cool stuff.
