Archer Man works well (at least on archlinux)

run "ruby Compile.rb"

or install the gems "bundler", "gosu", and "rest-client" manually (ruby-bundler, ruby-gosu, and ruby-rest-client on archlinux)

then you can simply start archer with "ruby Main.rb"

EDIT: bundler is not necessary for playing, just comment it out if you don't wanna install it

#require 'bundler/setup'
