I am liking it so far, I hope to see it continue to grow as a game in the future. By the looks of it I was wondering if you planned to add a merchant or a base building system for the dungeon game mode for the above ground or maybe a research system to find a way to teleport between every 10 floors if you planned to add a monster and loot respawn mechanism?
Also some personal requests would be to add a futa unlock in a "sex/kink/ or a "more-vore-functions" skill tree to unlock cock vore and more sex related stuff, and maybe more than one unlockable "choice of results" for the unbirth funktion giving choices like "churn into cum (basic digestion)" or "friendemize" have them slowly turn into a friendly unit over 100-200 movements/actions or a "pregnancy" tipe that digests them and then later over 250-500 movements/actions (to make it fair it would need to take a long time) can birth them as a customizable unit just like your own character but for customization past pred character species you would need to unlock another skill in the same skill tree to unlock "inter-species" or something I am not good with names.
And yes you can still eat and digest them later or leave them on the surface level because you can't take a entire army with you down the narrow paths of the dungeon BUUUT starting at a party limit of 5 party members you can spend skill points to increase the limit in a 1 for 1 exchange.
