This was tons of fun. Not only is this a really unique and visually appealing way of renewing a generally overdone genre, the way that "rebirth" (selling your pits) is implemented is also incredibly fun and unique. Excited for more to come!
I also want to note that I am a big fan of how automation is gradually introduced and used by the player. Needing to constantly fuel a machine hungry for the energy of burnt corpses so you can continue to make corpses is pretty metal.
