Crashes alot and u cant have a transparent background

soo when u use dither 6 and 7 the game crashes and u cant use a transparent background which is pretty bad and trash
P:Poli :P

Excellent but crashes predictably

Be warned that dithering type 6 & 7 always seem to cause crashes (using iOS 18.1), otherwise it’s a nice app with a pleasantly simple interface
