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.
Swap out openSUSE_Leap_15.5 for openSUSE_Leap_15.4 or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
