the fluidity games are motion controlled water-physics games though they're more like 2d puzzle-platformers, maybe give those a shot?

they look neat but i'm referring more to like, monkey ball or marble blast

ohhh, i think i misinterpreted your words before as meaning a fluid sorta game where moving around is as intuitive as rolling a marble around, not literally being about rolling yourself around like a marble. oops

those are nice too but i feel like we've got enough of that sorta thing. i feel that whole monkey ball "tilt the course to make the ball move" style of gameplay is pretty rare. i can't think of much else besides mercury meltdown

"tilt the course to make the ball move" being rare reminds me of how surprised i am that we don't really have a plethora of randomass higher-quality wooden marble labyrinth simulators/video games lying around, it seems like something easy to make even for shovelware but i don't think i've really seen it around

oh ye also for more 2d concept-adjacent games, and yet it moves and yoshi topsy-turvy come to mind for course-tilting being the primary tool you use to play, but again no marbles and no 3d and also the latter's fucking awful lmao

oh yeah that reminded me of one other - kororinpa on wii - that game looks awesome

yoooo kororinpa, that takes me back... that's one of those games that was on young teen me's bucket list but got lost to the aether at some point (until now that you reminded me of it too)
