I have only but myself :") So can't say much about how it would feel to play this with someone else. The ability to change the speed would make it fun since it is not only about winning but also the added factor of how close you can get to the other player and that is fun.
Getting completely together is really hard, but I played in the slowest speed just to Renko and Maribel together. Otherwise I wouldn't have make it
My favorite part: I probably should do a simple game like this to learn Godot or a game engine o.o (I'm taking notes 📝)
