MAJOR LEVEL EDITOR BUG!!!
If you place a lift (which I dunno what it does) in the wrong place, you can't then delete it using 'Undo'. Also, if you've moved the camera at any point, when you exit to the Main Menu half of it will have disappeared. It's kinda annoying.
BTW the game itself was very tricky and hard to get the hang of. Level 1 was easy enough once I got the hang of it, but by Level 2 I was simply throwing myself off the cliff just for my twisted amusement >:D
My suggestion is, make the Level Editor seperate (like, on a different website) but include a link to it. Then, you can paste the code into Notepad. You go back into the game itself, and use a 'Custom Level' thing to load that level and play it. I think that's a good idea. If you use it please credit me ^^
