Do i need to download the android version to play it on pc ?
No. Quote from FAQ page in the Wiki:
There is no Android version of the game. However, it is possible to play on Android using the PC version under emulation. Instructions are in the itch.io page, under the heading “How to play on Android”. It goes the same way other Renpy games are played on Android using joiplay. Youtube has videos showing how it is done.
Download the zip with Windows logo (or Penguin Logo if playing on Linux).
