Oh yeah, the back button shouldn't be I'm the mainemu, as that is the first screen in the game. Nothing exists before that.
I'll fix that. 👍🏼
The "Open" in tutorial is just there for teaching. But I'll replace it properly .
Number of pegs being unlimited has a reason. You need to hit ONLY the number of pegs shown in the background, but you can place unlimited pegs, so that you get an idea which peg location works for your purpose of reaching the exit. Then, after experimentation, you can restart and place the pegs in the right location you found by experimenting.
(Also, you can enjoy the random xylophone notes when marble hits the notes 🎶)

Thank you for reporrting the back button in main menu glitch though. I'll fix it right away 😊
