I think the main problem with this game is that the puzzle solutions are very easy to spot but the execution takes a long time and it is very easy to make a slight execution error and softlock yourself.
I think a rewind option would go a long way to make this more enjoyable to play and just a bit faster gameplay overall.
The puzzle design overall is a bit too simple in my opinion. It spends most of the time introducing new mechanics but never really explores them in a satisfying way.
The music and art are great tho. I especially like the UI and the scene transitions. It feels very polished.
Don't let my criticism discourage you. This is a great entry for a jam and you should be proud of it.
