It is very similar in gameplay to the 1982 arcade game Robotron: 2084, although filtered through Jeff Minter's distinctive style. The title screen gives the title as Llamatron: 2112.
This game contains examples of:
- Gotta Kill Them All: Every level requires you to kill all the enemies on the screen.
- Scoring Points: You get points for killing enemies and rescuing creatures.
- Spiritual Successor: From the same developer, Minotron on iOS, and with ten times the retro shout-outs and bizarre enemies.
