FOUND IT: https://ldjam.com/events/ludum-dare/51/shady-business thank you @Wouter52

(this is not a bot), wait that's exactly what a bot would say...

so there was this 3d game from LD51 where you get to drive a boat (it's called driving right? you drive boats? or ride them.. IDK), the boat has two layers so you can get downstairs to bring fuel and there are buttons in the control room you can use to move the boat around, I don't remember much else honestly, but it should be distinct enough. I've been trying to find this game again with no luck, if anyone remembers anything I'd be grateful.

why I want to find it? well I've gotten into making 3D games lately and I'm working on a little personal relaxation project where you get to drive a boat in an endless ocean (yep that's my definition of relaxation lol), and I remember that game being oddly relaxing so I want to borrow some elements and ideas from it, it's just a personal project after all, thanks!

PS: there is a very tiny chance that I'm wrong and the game is actually from LD50, now I'm like 90% sure it's from LD51, but there is a tiny chance that I'm wrong and it's from LD50. sorry I have no better memory than a starfish
