A bit of constructive criticism.
- It's very annoying to rotate tiles. It would be so helpful to just press R and have a rotated tile.
- Adding things like doors is so confusing. I didn't know you were meant to remove the wall and I spent forever trying to figure out how to stop it from clipping.
- The topdown view's fixed perspective is so annoying. There's no way to rotate the camera at all, so levelmaking is a lot harder.
- It's not made very obvious that this editor can only make levels, and you're unable to play them. I'm completely willing to wait until the game comes out to be able to play the level, but I never got told anything anywhere about that.
- You can't mute the music. It would just be nice if you could.
