Well, you can't. I tried many times and maybe there will be a video proof of someone making it. When the AI moves from the begging it is easy to reach corner one, then the second corner you have to move once they move as well and that's somewhat easy to reach too, but the third one is impossible.
And, besides that, this is a game jam project. It is not meant to be mastered, rather it is meant to be entered, felt, and finished. Difficulty breaks mood and the following frustration kills tension. Trust me, someone who has made over 50 projects over the course of 6 years and who has been part of game jams, the golden game jam rule is - Low skill floor, short runtime, strong aftertaste.
Edit: Good luck, once again.
