Thanks, Stomy. Good to hear from someone with fellow experience trying to make one of these.
I'm not happy with the hospital part either and it needs something different.
Enemy and weapons need balancing and melee need to find its role. I basically got inspired watching a John Woo movie to try add melee combat, but barely got it in before DD and had no time to balance it. I can kind of envision the henchman diving and ducking and rolling around like acrobats to make combat a bit more entertaining.
Next update should add secrets too.
Will check out fear for inspiration. I've always thought it looked really cool.
