Okay, so:
- There is no keyboard control to select tiles, you have to select them with the mouse. I need to do the same thing even if I just want to make a straight corridor.
- The camera is very bad, I can only rotate it 180 degrees.
- I can't change the position of the exits.
- I can't turn off the music.
The most important thing is the 1st issue. I just can't work in an editor where you have to select something in the menu with your mouse, which is why in all my prototype editors most of the control is on the keyboard.
