Fun game but hard as hell!

When do you acquire it? Ive been encountering doors and keypads for this level for ages but nothing. Do you pick it off the floor 4 boss?

Hello guys! Is it planned to port game to linux same as Gheistershiff and Ghost Tower?

If any bugs managed to crawl past the QA, please post them here.

Maybe I did not see a full map, or understand how to properly use "scan area" but it would be nice to be able to see the whole level in one view.
