Ahh, cool! I'll give yours a shot :D
Our game was TIME SKIPPY. We debated about how to use the "Only One" theme for a while: one-button games, "there can be only one" games. A cool idea we had was a game where you had to slowly give up your items and stats until you had only 1 heart, 1 weapon. But we ended up going with an action game where you move in one-second spurts, taking one action at a time. It ended up feeling like an action movie (which is why we love calling it John Wick-esque) where you're running around, using whatever's nearby to defeat your enemies.
I hope you like it! You can play & rate it here: https://itch.io/jam/gmtk-2019/rate/462635
