Yep, now any filthy casual can just download the game and double click the executable to run it :D . No need to use DOSBox anymore.
There is both Linux and Windows version available and I also released the sources in case you want to check out how some specific feature was implemented.
Over the original DOS release there are many small background changes and improvements and there are also a few gameplay differences in order to make the game more accessible. The destroyer weapon now only takes 15 ammo instead of 20 so it is more viable outside of boss fights and the minimap now also shows the player's line of sight and the location of keys.
