Hey Vufka,
Glad you enjoyed the game thus far. You mentioned you got stuck with the enemies? Can you explain what happened? Two known factors:
1: When I designed the stages I made certain screens have one tile away from the hud. Some how at the right distance the dash forces the players hitbox to reach the hud forcing it to the other screen. I adjusted some of the areas but I ran out of time to do it to everything else.
2: If you follow the path, say you went from one screen to another and it puts in an edge you weren't suppose to be in, sadly there's nothing we can do about it now. Its a current bug in NESmaker.
