Looks like I'll need to look into custom ROMs, but due to an intentional lack of consumer protections in Singapore, local banking apps and government-related apps are increasingly nitpicky and intrusive in blocking usage on rooted/custom environments...

I was playing on Extreme on my most recent playthrough. (had to use pause buffering on Master King Koco...)
The bumper hitboxes are really generous if you just keep them up, to the extent that I'm fairly sure you could going infinite. I think I managed to beat the pinball without losing a ball...

the pinball is... really easy, though? it's practically impossible for the ball to fall through so long as you hold the bumpers up
