Interesting idea.
The 3rd level feels very tedious.
It seems like you can beat a level by shooting the ball out the top of the screen. That was unexpected - not sure if its intended.
Thank you for playing!
Yeah, I fully agree with level 3, hopefully it didn't ruin your experience too much!
Yes, clearing a flag by reaching the top of the screen is intentional. Having it so that you can continue off screen made it feel like a bug, and respawning at the previous flag felt like a punishment.
So clearing the flag when going off screen felt like the best way of solving that.
