A downloadable game for Windows

Made for the Mirror game jam

You are a robot in a testing facility and this time you are testing out the latest supercollider superemitter hypergammatron (TM) laser gun. This lab prototype has a limited range and can't hurt a fly, but the laser beam has curious extraphysical properties such as bouncing further upon hitting glass/mirrors and allowing the wielder to do a fast zoom to the end of the laser beam.

Originally intended for this to be a parody of Portal with more background story and more levels but I've scaled it down and it has 3 levels for now. Might develop this further if there's more interest as all the pieces are there.

Controls are your usual FPS type of WASD keys.

Space to jump. E to interact. Z to go into bullet time mode, left click to zoom. 

Use V to switch  between first and third person camera and mouse scroll to control the third person camera zoom distance.

Install instructions

Unzip and run "LightSpeed.exe"

Thanks for your detailed comments! It was my very first game that I made in unreal engine, am Glad that you made it that far! The light was intended to have a limited range as it would be overpowered otherwise but that feature turned out to be very hard for players to understand.
