You've made some fantastic improvements - this version feels much more polished and thoughtful. The tutorial and level progression are great additions, and the new mechanics add meaningful depth. That triple reverse gem level was tricky but satisfying once I understood how the tracks behave. A bit more clarity on those rules could help players get there faster.
A couple of small usability tweaks could really enhance the experience. Moving the CLEAR button away from Start and Fast Forward would help avoid accidental resets. Also, an option to erase individual track pieces instead of clearing everything would make layout adjustments much easier. This feels super close to being mobile-ready - I’d definitely play it on the go with just these small updates. Great work!
