Hello,
For the first question, you can enable “Run in background” in the settings and it should allow you to tab out or move windows.
On the tutorial, I didn’t think to add it due to many games now at days having skills trees, but noted! Will look to do a small cutscene to quickly explain it.
I will look into making the collider bigger in light and bigger window so it doesn’t feel to difficult to trigger them. It only needs 1 coin to trigger it but because the size of collider sometimes it might not touch the coin.
Thank you for your feedback!!
