Roguelike
Solitomb is a demon-fighting prototype which mixes Balatro and solitaire, from the maker of Slipways
Slipways was the best grand strategy game I'd played in years, because it tossed out all the genre's micromanagement in favour of a strategy puzzle where all your exploiting, expanding, et ceteraing could be squeezed into an hour's play. That game began as a PICO-8 prototype by designer Jakub Wasilewski before being polished to a fine shine in its full release.
