[Server Request] Altitude

I'd like to request the addition of the game Altitude.

It's a very addictive low resource 2D game that has been free to play on Steam since a few years now and even though it's userbase isn't very big, it still has an extremely persistent community. (i myself am playing it multiple times a week since months, and only had a few longer pauses in the last few years, and i'm by far not the only one who sticks to the game like that). The game can be downloaded from the website for windows, macOS and linux (the Steam version is the same, but the files don't include the server launcher and configurator binaries).

Steam rating is: 93% of 1511 user reviews positive.
