I liked the graphics and sound, but couldn't work out how to get through the first door?
Also, i think that first puzzle where you have to jump and mid-air dash is too hard for the first level of a game. I'm still working out the controls and feel at that point, and the game keeps killing me with spikes and making me do the wall jumps again. It didn't feel very welcoming.
If you tell me how to get through the door, I'll come back and play again :)
Edit: Light the orb first. I missed that somehow :P
It's a nice game, but I think it gets too hard too early
