I made this game in 48 hours for Nokia 3310 Jam 3 (2021). The jam's rule was to stay within the visual limits of the Nokia 3310 phone.
That meant a base resolution of 84×48 and a palette of just two colors.
The restrictions turned out to be a blessing in disguise. I was doing the jam solo, and without an artist I was worried about how the game would look. At such a low resolution, though, my basic art ended up looking pretty nice.
There are trees, coins, ski lifts, speed-boost pickups, and plenty more in the game!
