sounds very interesting

but i dont know how to play :P

You don't know how to play this specific game? Or text adventures in general?

If you don't know how to play traditional (some might say 'classic') parser-driven text adventures, then one of my other games Deer Creek https://8bitag.itch.io/deer-creek will provide a better starting point, than this game, as it has a built in tutorial which will take you through the basic commands like movement, EXAMINE, SEARCH, INVENTORY etc.
