You've a solid game. I'd add arrows or some kind of indication to tell the player if he should first go this or that way. For example, if you go right and down at the start of the game, you can't go back up to clear the part you missed clearing on the left.

I'm glad you enjoyed the game. The hole is there to teach the player how to grab onto ledges (jump near the ledge by holding the button in the direction of the wall). Metroidvanias don't usually have tutorials with arrows because, as an exploration game, the player must explore and discover the path by expanding the map (if you pause the game, there's an option to view the map). Thank you for playing and for the feedback :)
