Our friends over at 'Braincraft Gaming' have been working on a game based off the 'Apocalypse Hotel' engine - Normally limited to mobile games this is their first foray into PC gaming and I think they have created something special.
WARNING: This game is incredibly difficult. If you find the later stages of Apocalypse hotel difficult you will not enjoy this game. It is a rogue-lite style game which features permanent death - That's right folks - if you die, you die. It's more about beating your high-score than completing the story (I've scored 516 - if you want to try to beat me)
I personally really enjoy games like this, and like Nethack, but make sure to read the warnings on their page before purchasing. I have released it on Steam for them and hopefully they will be releasing a mobile port sometime in the next 6 months... take a look at their page for more details!
