I also played it against myself and won hahahahaha
A xPC mode would be great, but I know that do this in a week is hard. Maybe a future update? I'll try to play again later with someone as enemy, but so far so good. Congrats!
I'm glad you gave it a shot solo, and hope you do try with another player later! We do plan to keep working on this post-jam, with the goal of getting at least a vs PC mode and/or online play working, just needed to focus on the core gameplay during the jam.
