You would need x86_64 Common Lisp implementation and Quicklisp installed.
Evaluate this in REPL:

(ql-dist:install-dist "http://dist.borodu.st/alien-works.txt" :prompt nil :replace t)

Clone https://github.com/borodust/notalone-thriced into ~/quicklisp/local-projects/ .

Then again in REPL:

(ql:register-local-projects)
(ql:quickload :notalone-thriced/game) (alien-works:run)
