Summarize your game!
Sunk Cost is a 2D pixel-art boss-rush platformer where every choice costs something. After defeating each of four bosses, the player must choose one of two ability upgrades - the ability they don't choose is passed on to every future boss, compounding in power the longer the player delays commitment. Players fight through a single connected map, growing stronger with each choice while simultaneously making every remaining fight harder.

Please explain how your game fits the theme.
Every time you defeat a boss, you're offered a choice between two power upgrades - but you can only take one. The ability you don't choose doesn't just disappear: it gets passed on to every boss you haven't fought yet. Getting stronger now means someone else gets stronger later, and by the time you reach the final boss, it may be carrying every advantage you ever turned down.

The theme isn't just a backdrop here - it's the core mechanic. There's no way to "win" every choice. You're always trading immediate strength for a harder future, and the game never lets you forget that the fights ahead are shaped directly by what you decided to walk away from.
