Thank you so much for playing and your review!
I agree about the save system.. it didn't even cross my mind to implement during development.
Yes that's a good idea about the reset button. I'm not sure if you used the "drag" functionality which is a quicker way to clear the puzzles, but not as good as a clear button -- I'll add it after the jam.
And yes I drew some inspiration from the Witness. I enjoyed playing that, but have memories of annoying frustration from it, perhaps I've caused that to other people with this game!
Regarding the "tutorialization", I tried my best to introduce the rules slowly, but after seeing yours and others feedback I think it misses the mark. If you have any suggestions I'd be very open to them. :)
Cheers!
