Experium by Patrick Martin

How to play:
Simply extract the folder and then run the Experium.exe found within.
Bear in mind the the design is very simplistic, especially the start menu.
The aim is to get as big a score as possible, by proceeding towards the right or defeating enemies.
Red orbs give you health, and there are 2 power ups scattered around the map, which let you either defeat an enemy
in one hit or become invulnerable for a limited time.

Controls:
A to move left, D to move right, S to crouch, Space to jump.
Hold Left Shift to run, or press Caps Lock to toggle it on or off.
Left Mouse button attacks and Right Mouse button blocks. 
Escape to open the menu.
