Yes, what makes it special is a sort of pixel based physics engine. Liquids, gasses, etc are simulated pixel by pixel, so chemical reactions and destruction of the world are simulated in a pretty cool way.
Extending on aski3252's comment - it's also brutal. There isn't much handholding at all, and its one of those "knowledge is power" games where you'll be dying a lot before you make any progress.
I highly suggest giving it some honest efforts before deciding it isn't your speed. I refunded this game after hating it for 15m, watched some videos that are aimed at new players / highlight wand mechanics, and then immediately purchased it again / threw 40 hours into the title since. I haven't yet won a run, but I know it's going to be fulfilling when I do, and this game opens up so much freedom once you understand the rules & constraints of the physics.
