Actually, the web version I just made it to give the player an introduction of the game, and I wasn't sure that the web version will have unique bugs or not, so I just went in safe side and made the levels not playable only when downloading it, also because it was the last hours in jam so I don't have any time to fix anything I just got time to make the game page and publish the game.
Anyways I hope you downloaded the game and enjoyed it.
