This game was (and still is) released by its developer as freeware. As such, it can be downloaded from the developer's
website.
For future reference, felix ferris, Abandonia doesn't deal in freeware; its sister site,
Abandonia Reloaded, does. In fact, they already have the game
on their site! Also, if you want to get another freeware game onto Abandonia Reloaded, I highly recommend you
sign up for their forums (or use your Facebook or Twitter account to log in), read and do everything in their
request guidelines thread, and post a request in their
request forum!
