Maybe you can try to do safe speed runs for the others like just fast normal speed but solving them without any mistakes etc. It will at least be a good timethayneq wrote:yeah I'm actually afraid of breaking the other puzzles. They weren't really designed to go this speed!
Please take care of your puzzles and do not go faster than what the puzzles can handle! i think a solving attempt without doing a mistake and going the fastest way all the time is enough...
