If possible an undo option in the editor to undo the last change you made. So a single click could be undone. I have the bad habit of getting out of test mode, being on the default tile, and click-dragging across the screen thinking I'm still in test mode. Or maybe a null tile could be added that does nothing. It could be the default tile when exiting test mode. Sometimes when placing a and then testing the level the tile doesn't appear. Just some more suggestions.

That light is very intense and distracting. Giving it a shot though . . .
Tried click and dragging the orb but it doesn't seem to work all the time or go past the flashing light area. Figured out that the orb must be on a tile for it to be able to move. Maybe you should include that in the instructions just in case someone else doesn't realize it. I thought it was a game with a ball floating in space similar to the space golf games.

The final game will for sure have instructions, I just didn't have the time to throw those into the alpha editor. Thanks for the feedback though!
