MidBoss version 1.0.4 is out now, containing detailed stats, new Steam achievements, and most importantly the new death cards! These cards are generated upon death (or beating the game) and contain detailed data about your run and how it ended. They even contain your entire inventory! You can share these images with your friends or on Twitter, and import them into the game to view the detailed information and replay the game with the same seed and settings.
