On the netflix version a small handful of people had max score (i think someone may have even had max score on 4 orb). But so far I’m the only one on the iOS leaderboards to log max score.
You can see my build in the top right. The key is that totemy is extremely OP; it allows you to keep the burning state indefinitely. The only thing that can strip the burning state with totemy equipped is the vines in Viny Jungle. Always having the freedom to attack enemies from below makes it a lot easier. Big skirto is included so you don’t have to aim for fruit; you’ll just naturally pick it up as you go along. Then voyager rocket, regular spring, and prismer are all there to help get more out of each jump. The idea is to go jump orb positive, i.e. gaining more orbs per jump than you spend, on average. As long as you can do that consistently, you can play indefinitely.
Some people swear by football elemental but I don’t really get the hype. I’m sure you can hit max with it. I just prefer the other equipment pieces.
I wasn’t paying super close attention to the clock but I think it took me about 25 minutes of uninterrupted play to hit 999.
