This is super fun. I want to try it out co-op at some point. I agree with some other people that clearer UI would be great. I really like the doodle aesthetic too. Great job.

You could technically play it co-op, have one person on the mouse and one person on the keyboard. Obviously co-op isn't intended and I actually think playing it this way might actually be harder than controlling the two characters on your own, but its an interesting idea and maybe I could make the game much more co-op friendly if I tweaked it a certain way. As I mentioned before, the UI was slapped together in ten minutes and I regret not spending more time on it, the doodle aesthetic is also kind of last minute but it worked out much better and I'm glad you liked it!
