Hadr is an indie puzzle game that one would, I suppose, mostly describe as physics-based, if we were being very dry about it. You are a cloth, or several bits of cloth, depending on the level, and anything that you can cover up will vanish. A birdcage. A lamp. Most of a sofa. Whomph. Gone. I suspect is intended to be melancholic and floaty.
Except. Except. I found it incredibly sinister.
