Once I saw that I needed to be in full screen, it was a lot more fun. Controlling the ball by bouncing and judging the distance was really fun. But I agree that this definitely needed a restart button, or at least automatically restart when you lose. I didn't want to keep playing because pressing escape twice (the first time just exits full screen) and then having to go back into full screen started to add up.
The visuals were solid, a simplistic style done very well. A fun game, just needed a small QoL change!
