Thank you very much for the reply, did you downloaded it from itch.io? Maybe give it a try downloading it from our website (worldofsisters.net) And there should be no installation as the whole game is just in .zip file, just unzip it and in the folder you would find World of Sisters.exe file which starts the game. Hope this helps you. If not can you please send us a screenshot on projectworldofsisters@gmail.com Big thanks!
