Have I missed that sign that was explaining the resizing of the slime or there simply wasn't one? 'cause I had to come back in the comments to figure out that there was this on-screen tools. And except when there was that first opening requiring to be thinner I didn't had to used the scale which was an awesome concept for a platform game there could have been so many more specific passageways requiring the right shape (instead of that fun parkour down bit). Though small isn't always the best option since funny enough the tiniest ooze was been hurt by thon own jump high. XD
