I guess widen the concept to “chaining”. Like puzzle games where you score combos for chaining things, or some kind of dominos-based physics games, or maybe a game about pouring jugs of water into different waterfal cliffs to attach enemies at the bottom of a cascade of cliffs.
dunno. I’ll see what happens. I usually suck at these because after a few hours I realise the game I’m making sucks or I get sucked into a rabbit hole focusing on unimportant things
