It wasn't made within 3 hours haha
It was originally supposed to be for Trijam, but my artist disappeared and the core gameplay needed more time to program and bug-fix. The art for the three rocks and the pickaxe was done by Haiyoooo for the jam, the rest of the art was public domain assets just thrown together quickly, not a polished aesthetic.
The three star point goals are my high scores (rounded down to the nearest multiple of 500) after playing each level 2 to 3 times in testing (which consists of a starting two grids with the aesthetics and row order randomized).
It's meant to be rather difficult, with high strategic depth. The dynamite can be managed by grouping it up early and destroying it when your score it still low to non-existent, and/or by high-level board management, shifting the dynamite around so that it can't form. By moving not the element you want to match, but an adjacent element you want to relocate orthogonally, you have a lot of control of the grid. But it's definitely rather difficult / strategic, which I like. I've never really been a fan of typical Bejeweled-style match-3 games where you simply slide an element to an adjacent space to match, but here with the orthogonal movement you can do quite a lot more.
