Charming little game! I got to 225 after a few tries. It gets tricky!
Also, there is periodic tearing at the top of the screen where the score shows. It looks like music might sometimes delay resetting the x scroll register back to zero, so moving the reset before updating music (perhaps in a vblank handler if not already) could be a way to avoid that.
Hi! Thank you for all the effort.
I'm still investigating the causes of this flickering and your response helped a lot! After the changes it stills flicks from time to time, but not as frequently as before.
I have some more guesses that I'll try later, before another update. I'm getting used to the limitations of the gameboy, but it is great to make a game for a 37 years old console.
