Ellipsetron is an arcade/fixed shooter inspired by the games Tempest and Gyruss.
In its core, Ellipsetron is an arena shooter. You are controlling a ship and fighting against endless hordes of enemies. However there is one unique twist, you can't move freely. Instead, your movement restricted by two elliptical orbits. When your ship is located on the first orbit it can shoot towards the center of the screen and when it is located on the second orbit it can shoot outwards the center of the screen, killing enemies behind its back. This movement restriction in pair with specific enemy behaviors creates a unique game dynamic.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Ellipsetron, simply use the following command:
