About
Omega Race is a 1981 shoot 'em up developed and published by Midway Manufacturing for arcades, notable as Midway's only arcade game to use vector graphics. Torrega Race is a space shoot-'em-up written in Lua using the LÖVE framework, inspired by Omega Race but explicitly not meant to be a strict clone of it.
How it differs from the original
The game intentionally diverges from Omega Race's design — for example, using different enemies — rather than reproducing it exactly.
