I havn't been able to play the game, because in the menu after opening, I click load and the message appears. I will send the file if I remember, but it's 23.1 MB (24,279,958 bytes)
I managed to track down the bug thanks to your save. I have uploaded a new version (with your name in the credits) and hopefully saving/loading works now. If there are still issues, it would be great if you could send another save file. Unfortunately, your old save file that you sent will not work with the new fix but hopefully there will be no more crashes.
