From mid-November to December 31, 2014, we in the KolibriOS project held a competition for game developers . For a month and a half, you had to write a new game for Hummingbirds (or port your own existing one). The “sources” of the game (including all the “resources” - pictures, sprites, sounds, music, if any) should have been posted on the SVN project under one of the open-source licenses. The game was supposed to be compiled from source using the Tup auto-build system on the KolibriOS server.

In total, 7 people responded to our call, who created 10 games for the contest (one participant wrote as many as 3 games, another one - 2 games; the other participants wrote one game each). Today we bring these games to the court of Habr's readers, and ask you to vote for the ones you like. To play competitive games, you need to download the latest nightly build of the distribution package from the KolibriOS website (“Universal Flash / HDD Image” or “LiveCD Boot CD”). The games are located in the / KolibriOS / games folder. You need to download the Russian assembly, since some games (having an exclusively Russian-language interface) are present only in it.

TL; DR: If you don’t have time, opportunity or desire to read all game descriptions and play them yourself, but you still really want to vote, you can watch a video review of games from independent blogger Cyril Leifer, and evaluate the games based on the video:

Description : (according to the author)

The essence of the game is quite simple: you play as a geometric figure (at the first level it is a triangle, then at each subsequent level one vertex is added to you), which can only jump. It would seem that everything is elementary, but sometimes it is difficult to make a quick decision whether to jump or not to jump.
