"Mechanics Touch" - Lemmings-esque game for Android; Anyone know it?

[Prob Lem]

I just stumbled across a Lemmings-style game for Google's Android platform, https://play.google.com/store/apps/details?id=com.mechanics.engine" class="bbc_link" target="_blank">Mechanics Touch, from a developer named OrangePixel. It seems from https://www.youtube.com/watch?&v=whZOIwOSTbY" class="bbc_link" target="_blank">this video that, rather than assigning skills, you instead manipulate particular parts of the terrain, in order to allow the little guys a safe passage to the exit.

I haven't heard of the game before, and unfortunately, unlike most of the other releases from this developer, there isn't an ad-supported version to try out (which, given that some of the reviews mention crashiness, I would find essential prior to paying out any money for something). I was just wondering if anyone here was familiar with it, and, if so, what the consensus is on whether it's any good or not.
