Great demo. I'd love to see this fleshed out. I think a lot of the older games had seriously good playability and deserve to be revisited.
This is brilliant. One of my favourite games growing up was Thrust on the BBC Model B. Had directional velocity and towing mechanics, which was pretty good for the time. https://www.youtube.com/watch?v=Dt44PEIWBRg
Author here. It started as a technical demonstration for fluid dynamics in the web browser. Then I saw the js13kgames competition and the decision was made to make a game out of it. A game in which the fluid mechanic counts. The decision for the Lunar Lander genre then was quiet easy. Does someone know more games then the two I mentioned in the README (Plasma Pong and Pixeljunk Shooter) with more or less realistic fl…
There’s always the classic Liquid War:
Also, sometimes adding an official name for each map somehow make the game look better. Nice game, I must try again because I lost all my ships in the "volcano" level.
Edit:
Putting the light to show the vertical speed in the landing pad may make more sense in universe.
Also, the buildings look very similar to the old gorilla.bas game :).
It would be nice to be able to disable the simulation in the introduction and final screen, so I can keep the page open to play later, without using too much battery.
Lander used to be the first game I would program when I got a new computer as a kid. I remember writing it for the TI-99/4A, Commodore 64, and the Amiga 500 (in Modula 2). Your game brings fond memories of those simpler times.
Amazing what you can do these days with the tremendous speed of computation available on modern hardware, even with the js13k constraints.

It would be nice to have a vertical speed indication in the ship or nearby. Perhaps some semaphore like lights in the bottom of the ship. It's difficult to look simultaneously at the ship position and the speed indicator. Also, sometimes adding an official name for each map somehow make the game look better.

When I designed the buildings I thought actually about "Save New York" on the C64.
Earlier quoted context omitted.
On my computer the game runs at 40 FPS. So there is still room and I can increase the timestep if you want. This game simulates the Navier-Stokes equation on a grid of the size 256x128. Four times the size would already reduce the game to 10FPS or even more. Of course you can try to rewrite it to run on the GPU. An alternative would be to use so called Smoothed Particle Hydrodynamics. This is particle and not grid ba…
The problem with higher speeds were instabilities in the numerics. So I reduced the internal time step. Never tried to increase the speed again after solving a few of those problems.
