Interesting idea, I think I can see what you are going for! Unfortunately it glitched out a minute or two in where the camera stayed still and the player moved out of view, so I couldn’t keep playing.
I think it would be better if you onboard the player more, rather than just have a big screen of controls at the beginning, which is a lot to remember. I couldn’t figure out what Split or Merge did, so I ended up just shooting and moving with one character. I know there’s limited time in game jams, but spending some time making an in-game tutorial I think would make a big difference. Good job!
