Very cute level design with simple and easy to understand gameplay. I did have trouble with the patience level (even with the advice you mentioned above) but I enjoyed what I could get to. Extra kudo's for releasing the source code.
Thank you for playing. I don't think that level was thought through well enough myself. If you still want to play the ones after it, the file "utiles.ini" has a field called "level_beaten" that you can manually adjust to skip levels.
