I didn't find this one too bad. I actually quite liked the 'hit switch, run to lift' nature of much of it. I didn't get myself trapped behind the bars but I did wonder if there was the potential to. Guess it's good that I didn't try. I did get crushed the first time I tried for the invisibility powerup on the platform in that room though, which was a good laugh :).
The leap to that door was unclear, especially when you expected the teleporter to be a bit more helpful - still, at least it made it FORGIVING, and so much less unpleasant than the 'Boy Are My Arms Tired' puzzle! At first I wondered if they were requiring us to do a tricky grenade jump ... it took a few times for me to realise what those side platforms were there for.
Anyway, at least this one got me moving again after being stuck and uninspired with Tired Arms. But still, what I wouldn't give for a large open space! Trojan has made me realise that M1 really lent itself to narrow corridors far too well.
