Perhaps it was unintended, but for example with the bat powerup and nothing else I could set blocks to get past the gap in the right section of the first room. The extra horizontal height can be enough to make some jumps that you couldn't before.
Oh yeah, I found that as well. It's definitely not supposed to work and I plan on fixing it, but also at the same time allowing people to skip around a bit isn't too bad too if they know how. Just a shame the area it leads to wasn't finished in time. I have every area sprited out just not coded.
