Yes, I found the link to the source code on Github on another website.
I play the game with a 32 bit executable .x86 which contains the pck file.

This works perfectly for me.
Thank you!
I am using MX-15 Debian Jessie 32 bit
It's the same for me as I've read in some places on the internet: at some point, I lose the motivation to continue playing. I feel like it's always the same thing over and over again. By the time this point came, I had already been playing for almost an hour. Getting back into the game a few days later proved very difficult, as I no longer knew where I was and what I had to do next.
There is a point where I throw the box two squares. The box in the screenshot came from the top left and flew one square further over the bench.

I'm not sure if this is a bug or if it's intentional. Since I didn't realize beforehand that this would work, I had to think about it for a long time.
Best regards
