Go to the game install location, copy the game folder, and put it somewhere else. Not a single game in existence needs installation, everything is self generated after running the game exe file. That is if you have all the files in the game folder. Everything outside is irrelevant, besides maybe some default dll stuff that it finds from the windows folder, and if it needs a store app where it was downloaded (and that you have bought the game with that store app account).

Well the exceptions to that would be that in terms of drm, this one doesn't have any drm, so you don't need itchio to run it.
Other games might try to force run the store app before launching the game, so they check if you actually bought the game.
