The PC DOS (1991) version of this game was the first port I played - ah memories! A great game that has everything you need: cool graphics, neat soundtrack and gameplay that is challenging without being too hard so that you keep coming back to play it. Once you got used to the janky inventory system (you don't just pick up an item and that's it, you have to pick it up and then move the selected item slot highlight to a blank one, otherwise the object you pick up will drop back onto the floor immediately) you were away. Great graphics, playability and presentation make for another Bitmap Bros classic well worth your time. I am surprised this game hasn't had more votes as it is easily on par with their best game, The Chaos Engine. Anyway, if GOG do add it to their roster one day (PLEASE!) it doesn't take much to get it working in DosBox. Either that, or they could somehow wrangle getting the GODS Remastered version by Robot Riot onto GOG? It is no longer available on Steam.
