Breaking change! Upgraded to Pyxel 1.5.1

Hello folks!

As you may have noticed Pyxel 1.5.1 has been released yesterday. But I saw that it made a few major changes that broke our game. So, today I modified the current distributions of the game (windows.zip and source.zip) so they can work with the latest Pyxel.

For those who won’t run the source code, you can keep with the previous Windows distribution, or download the updated one. No big changes were made on that executable.

If you prefer to run the Python edition (source.zip), read this carefully. Since today, we have pinned the Pyxel version we’ll support (see the requirements file here). To run the Python file, get sure to have that version installed.
