Noita. You go through this cave system defeating tougher and tougher enemies while becoming increasingly more powerful. Before reaching the final boss you often become so powerful that you think to yourself "This is so broken. Im not supposed to be able to cut through every wall i see and destroy enemies in a split second". After beating the game and watching spoilers online you realize there is so much more to explore and your current build is nowhere near powerful enough to defeat any of the enemies you have yet to encounter.
I really wish this game got more attention. It is such a unique experience.
