The art is well done ( nobody pays attention to the detailed ground, they just care about the slime ):< ), and the "remapped controls" mechanic isn't as annoying here as it is in other games. Sometimes I ended up playing Keyboard Twister, which I think you should capitalize on if you develop this further.
However, sometimes the controls are mapped to...troublesome keys, like the function keys or Enter. I didn't have too much of a problem with a function keys, but sometimes I just outright couldn't see what key was chosen! And, at least for me, sometimes I get randomly teleported somewhere. In one particular instance that I ran into both times I got there, I teleported into a wall and got stuck.
This is another one of many games made during this jam that deserve further development. Keep it up!
