Hey Darius256, thanks a lot for playing Wheevil!
I will definitely communicate better the dash availability, maybe make a separate tutorial chamber dedicated for that. I have updated the game with properly drawn and animated character, so maybe it will help. In the version you played, the character turned blue when the dash was used, and the dash can be used only once before touching the ground.
Regarding the doors — I am planning to use them for a few metapuzzles, so for now saving their unlocked state only after you leave the chamber. I will flesh out more of the world itself, and revisit the doors, maybe this behavior won't be necessary
I am trying to find a proper balance between it being ruthless precision platformer, but at the same time I am planning the main route to be accessible for players new to the genre (hence that current tutorial stretch in the beginning, and fixation on some repeating maneuvers).
And, of course, thanks for the comparison with N :)
