Just finished up Duality, a stealth action game for 7HFPS. It took about 12 hours to finish in total, but I'm super happy with how it turned out. I'll probably not do a 7DFPS project this year, but I might polish this game up instead.
If you want to wield some space ripping powers and sneak past some robot knights of death, check the game out here: http://itch.io/jam/7hfps/rate/13201
Oh, and do rate it!
