This is the first puzzle I have made - I wanted to try and use walls but I think I started out very simple. I was going to try some sort of spiral puzzle, but I think I will get to that once I get more used to the editor.
Now, onto my puzzle. I am not sure how hard it is - as I made it I pretty much only see my way as viable. I can do it in 1 move, but would like to see if there are any other ways.
(Store in Tidalis\RuntimeData\Logic\LevelFolders\Custom, and then in Tidalis click Play -> Puzzles -> Custom -> Plivesey first puzzle.dat)
Edit: Included a screenshot for those who might want to see it before DLing it. (And no - it isn't set up for the solution... or is it!?)
