This is sort of like a bite-sized 2D version of Shadow of the Colossus. (Despite what the name may lead you to think, it doesn’t actually have much similarity to Dark Souls.) You play as a tiny human fighting massive monsters, with some environmental storytelling hinting at surrounding context.
Here’s the most notable about this game: You only have one hit, but so do the bosses. One hit to their weak point and that’s it, you’re done. This has blown my mind in regards to how I think about game design and game challenges, and I’m going to vomit those thoughts at you now.
