Pretty tough: it took me fifteen minutes to figure out how to get through it. Not broken, I don't think, just closer to optimization. You will probably be able to find this route or better.
Ha, I see where you used the trick. Nice integration with the reverse lock! That formation is so useful, I've been messing around with it a lot. You can use that formation in a ton of ways, as part of a lock or in a long path, to force really roundabout routes. btw the level is rediculous 0_o
EDIT: I think it\'s fixed now. I can see what I have to get around, just not how. If you want another big trick type level, play Always Another Possibility under my account if you haven\'t already
EDIT: About 12 off now.
