FANTASTIC level. Getting a 108 isn't bad, but the last 4 steps require quite a bit of thinking. Superb visual design, superb puzzle, really fun to solve... a 6/5 in my book.
Fantastic idea! There's one aspect that makes it a lot easier than I think it could have been (unless there's something faster than 104) but super cool nonetheless. I've been hoping to see some hole-less levels with restricted blocks like this.
