Cool concept! I played this for a lot longer than any other jam game so far, but I eventually got stuck on a level that seemed impossible. Maybe you could add hints to the game for people who get stuck?
I think optional hint systems are great! I'm not sure what I would provide as a hint that doesn't give too much away... maybe the placement of a single critical block, like a T or an X piece? I think this would be a great addition if good hints are crafted. Thanks for playing!
