I made it for the jam so I prioritized entertaining players in 20 seconds instead of penalizing them :D. Do you think it worth making a competitive version ?
you prioritized well. Focusing on a session of 20 seconds (or 100 seconds maybe in my case) worked well. Probably best to increase legibility if you want to invest more time. This is the cool thing about 20s jam, you can keep it as simple or complex as you want.
