Thank you for your feedback!
In some puzzles, there is usually more than one solution, because it depends on your creativity with the given operations. So even though I designed puzzles according to my solution, additional operations weren't intended on some levels. I'm glad you can solve with less than needed operations. That may be an achievement idea (if it would be in Steam someday) :D.
Yeah, as this was a short jam, I couldn't make more cutscenes, so it got dark in such a short time, but I'm glad you liked it nevertheless :)
