Nice, but two issues:

1. with a high resolution screen, the arrow is too small and I keep losing it

2. No idea how/when it saves. Sometimes I spent 20minutes in it and when I come back I get back to the situation I was on at the beginning of the session. Pretty disappointing :(

Tested on linux.

Thank you so much for the report! I think I can add a custom mouse pointer sprite to the game, also will check the saving algorithm. As of now the safe function is called when the game window is deactivated (including when the close query is started)

In v.1.6.2 the save function will be called every 30 seconds
