Easily one of the best games I have tried so far in this jam. It's simple yet fun and well-designed, fits the theme perfectly, and very original. This is very clever concept with just a few elements and mechanics, but combines them in very creative ways to create interesting brain teasers. The level design is really one point here, and as a puzzle game fan I must say that if this idea gets explored further and developed into a full game I would be really glad to play it through.
And as a bonus, art and music are done well too.
My only one minor complaint is that there is no undo button. Not much of a problem in this case since the puzzles are fairly small, but still would be a nice quality of life addition.
Great job! :)
