HOLY HELL THIS GAME IS GOOD
It's a bit like Lemmings, in that the point is to get from point A to point B as efficiently as possible. The physics generally works like you'd expect, but there have been a couple times where my structure couldn't support itself even though I was sure it would hold. Everything's kind of "floaty", meaning your structure won't crumble very fast. You'll see it wobble for a few seconds, giving you ample time to add a support or two. Even then, I find myself not being able to react quick enough to save my tower or bridge. Thankfully, there are many do-overs that let you go back one more (so far I'd say each level has between 5 and 10 of them).
This is a wonderful game. The art style is charming, the concept is unique, and it's generally fun to play.
