RUN is a unique and interesting game and gameplay, kind of like an endless runner, except to traverse the games obstacles, you'll need to flip gravity instead of jumping! [2K34CF] Ver 1.5
I'd think one that most people wouldn't expect, or that hasn't been used a lot in other works. Perhaps one where the player doesn't know what the character (he's playing as) is searching for, or wants to obtain, but you slowly get clues throughout the game as to what he wants.
That's the storyline I'd put into an exploring game like that. (Also, I really like that awesome treasure chest) :)
I will be taking a little break from programming to play Shovel knight: Specter of torment. (It's going to be released at 10:00am) It won't be a long break, but it will be a break.
