Camera controls:
- Not being able to look straight downs feels constraining
- Changing the zoom is slow - takes a lot of mousewheel turns :)!
- If you zoom out and look along ground level, half the screen is just blue
Fixing this might be a bit tricky - a suggestion:
if we say that looking straight across is 0 deg
only allow the camera to go to 0 deg when near the center of the board
As you zoom out, constrain rotation so that you are looking more and more downwards
At infinity, you would be looking down at 45 deg.
I hope that made sense :O!
Nice little toy game!
