Added cross-platform Pyxel executable

Hello gaming lovers!

I’m glad to announce that, since now, every users (from all the operative systems) will be able to run this game! Follow these instructions to do so.

First, install the standalone Pyxel app (which doesn’t require Python), and download and extract the pyxel-dist.zip file from the main page of our game. You should see a pyxel-dist.pyxapp file now.

Then, open a terminal, go to the directory where pyxel-dist.pyxapp is, and run this command:

pyxel play pyxel-dist.pyxapp

And the app must run!

NOTE: Get sure to install the same Pyxel version than specified by the game’s requirements!
