Yes, I thought about this approach, too. But me, I prefer keyboard for gaming and I wanted to try the retro-method of games like Gorilla where you entered the velocity and power and then you tried to hit another gorilla with a banana. But you’re absolutely right that the method you describe is a nice alternative.
Thanks for reaching out!
Ah, and for the palette I searched a long time, so I’m happy you noticed it. :)
