Five Stories REMIX fix & Upcoming Shock Block change

Man, I am on a roll with messing this thing up. It's not so bad this time as the problem only affects one stage, Five Stories REMIX.

The problem is that crush blocks will often not fall, even though their support block has been destroyed. This is caused by the lower blocks being misaligned. I have a script that snaps everything to a grid, but I have to manually turn it on and off while I'm editing the level, and apparently, I either forgot to use it in this stage, or I did, but then moved things around by accident.

Anyways, it's fixed in the 2.21 update. Nothing else has been changed.

I plan on updating the Shock Blocks though. Currently, you can't swat them away with a melee attack. You have to either push them away by throwing a bomb at them, or just move. Personally, I like it this way, but nobody else seems to. So in the next update, I'll change it.

Also, I plan on adding some kind of small visual cue to let you know that your yarn bombs are ready. You can tell by looking at your aimer arrow (it fades out when you have no bombs), but it would be nice to have something more noticeable.
