If you like classic and retro video games, especially those based on 8-bit, you are sure to love it. cecconoid. And no, it is not a title from the past, but it is a video game inspired by the old ones, but very modern, since it was presented in 2019. Of course, it is free for your GNU / Linux distro, and you can install it easily being among the repos and app stores in its DRM-free version.
If you want to know more about Cecconoid, it is a shooting video game with that primitive aspect, but that does not detract from anything of appeal. It is based on a story that begins on April 15, 2088, in which the ship Equinox is under attack by Stormlord and his robotic minions, the Exolons. You are the only hope for the crew, so you must save the fleet by overcoming a series of screens and winning the battle against your enemies. To do this, you must pilot the Samurai-1 fighter, finding Captain Solomon's key, clearing the covers of evil robots and saving Equinox from destruction.
Cecconoid is inspired by those of 8-bit, as I have said, and specially designed for handling with joysticks and divided into screens. The stage will be an alternative dimension where the pixels are the protagonists and the stages are still in black and white.
If you are interested, you should know two things. On the one hand, its developers advise if you have epilepsy problems, since, although it is in black and white, it uses a multitude of flash effects. If that is not a problem and you dare to play a game, you can see more information about the payment title on their store site Steam or visit the page of GitHub, where you will find its source code for the DRM-free and free version.
