+# MeatSlicer: A Butcher's Descent
+
+**Clear, harvest, descend.**
+
+MeatSlicer is an endless top-down arena roguelite. Play as the Butcher, clear rooms of flesh-hungry horrors, draft mutations, assemble grotesque item builds, defeat each floor's boss, and keep descending until the meat wins.
+
+## Play
+

+
+## Test and package
