You extract the .zip and click the .exe file.
but OP said he BOUGHT it which most likely means OP paid for it on Itch because the Play Store version is free and you don't have to buy it. Just a thought.

DRM is a game store like Steam, Origin and UPLAY. DRM free is just a launcher or straight up executable for the game.
