Install game from epsilon-1-01-setup.exe

Before running.....

This game is meant to mirror old-school, 8 bit
graphic games. So, you will need to right-click the
game file (epsilon.exe) select properties and then check the boxes:

Reduced color mode 8 bit (256) color.

Run in 640x480 screen resolution

Disable display scaling on high DPI Settings.

(Without changing these settings, I could only run the
game in a small window in Windows 10)

There is a pdf manual included during installation.
