Hmm, here's some quick thoughts.
- Add a tutorial level that's more simple and teach the player they can walk on walls.
- Make the rotation of the main cube snappier.
- Some fanfare when you connect a chain.
Hope that helps at all, good luck!
Thank you for your fine tips for improvement, I'll absolutely add all of them into the game. I'm thinking the chains will glow for a moment when you connect it.
