I'm glad that you made it till the end, I really appreciate your time.
regarding "wall jump and get back on the one block ledges" you can just climb by pressing Z and keep moving up.
and about the last coin, there is a hidden passage in the same stage when I first introduced the dash gem.
"reset option" is a really great suggestion that is really needed for this type of a game.
I agree that there are a few buggy stuff, and hopefully I'll be able to fix them soon.
thank you again <3
