Thanks for your feedback, it helped me to think of how others may perceive the gameplay. I went back into my description to add some more details that may help people understand to better avoid some of the confusions you experienced. Locking a Cube was designed intentionally but I did not think about how one could feel punished by accidentally locking a cube and then wanting to unlock it. That should have been an obvious choice to design so thanks for that. I can edit that into the design after the Jam is over since it was not part of my original intended design. The only way to unlock the Cubes is that if the Puzzle restarts, which is done upon checking the Puzzle conditions where you restart the Level or go into the Menu to press the Restart button. I also could have labelled the Puzzle name and hint, which are just floating as an abstraction.
