That would probably work. But I am not able to program such a game with PuzzleScript: I am mainly a board game designer, and video games are still more of a hobby of mine to try out new ideas.
BTW, a game app exists for my original Strata-Gems game, designed by a friend—fellow designer and developer Riccardo Foches, AKA Rifo.
I still prefer puzzles with individual levels crafted by the author, but to each their own: https://play.google.com/store/apps/details?id=it.rifo.stratagems&hl=it
