Played through it and experimented around. Awesome start, and it has great potential. Gave me a slight Overlord vibe I appreciate. Really enjoyed the strategic elements and I can't wait to see where it goes. Same for the story.
My biggest suggestion would be to reduce the duration of the infusion pregnancy. As it stands it's the energy cost and slow progress makes it not worth doing especially with the lack of experience gained during the pregnancy. Reducing the energy cost, or accelerating it to taking off a full trimester would greatly help incentives using that mechanic. Regardless the natural progression needs acceleration as well. You have roughly a 120 days before end game so it's not even possible the get through a pregnancy without infusion. Something like a 2 week/day natural progression and 3 month infusion or 1 month for normal summoning energy cost would make that mechanic much more usable. Some form of experience gain during pregnancy would help too.
That one is more of an observation then a suggestion, just noting it in case. The other current issue with the infusion which is that the summing RNG makes it just be diminishing returns at the moment. Even using saves as a cheat to reroll for good mates from the slave market and leveling them up, I didn't actually get anything better then the infused offspring. From my observations Willpower only seems to help with passing along the base characters stats and doesn't take into account the partners stats, because every combination only seemed to reduce the offspring's base stats compared to the better parent. I hopeful that adding additional partners to infuse will solve this with more variety, but it may take some RNG tweaking.
A couple of possible bugs I noticed:
-The population cap for the Hamlet caps at a 1000 before you even got all of the upgrades, and the housing seems to have no effect at all as of yet, for both the canines and felines as well as humans.
-Same for the food with no effect. Tried to go the evil route to see what happened. (Dark Humor Warning) You make a lot of money when you let people freeze and starve. Points for the realism.
-I did have a slave market girl randomly become marked for incest for some reason. Not sure what happened there.
-You lose all rewards for skipping the battle which makes gaining population difficult if that is the end goal, not sure yet.
-The Calvary is overpowered. You don't need a single tower to defend, and they didn't take any damage during the battle. I had to try to loose.
-I have to have to game in full screen for the menus to work properly.
-I noticed an inconsistency in the size of the character images in the chambers menu. They're consistent in the windowed game but full screen they are all over the place in image size.
Figured I mention these in case they are bugs and not just work in progress or on your radar. Hope all of this is helpful. Keep up the good work you're doing great.
