Thank you! You can enable easy mode from the settings that gives you 2x hearts to reach 2400 easily, give it a try if you haven’t already.
Hm, and now I'm getting issues: I cannot pick a bonus on 800 meters. I've even downloaded Linux version (twice) to test on two different computers and as soon as I get the menu the game stops responding to arrows. Sorry, I don't know how. Only once in four times I was able to pick it without the bug. I guess I started doing something wrong.
