Heya, I've been playing this game way too much lately, it's really really damn good so I'd like to share all of my thoughts ^^
The gameplay loop is really well done, i love the various types of attacks there are and the balance between draining/defeating enemies is a nice touch from other rpgs where you just focus on doing as much dmg as possible.
The bosses are really well thought too, they're more than just "regular enemy but better stats", they require some strategy and that's nice (again, it's not just "out-damage them and you win)
The random events is a nice touch to make regular fights less repetitive, i especially like the hunter, he sticks out as a "regular guy, but so competent he's actually the biggest threat"
It's also really nice to be able to have some of the enemies's attacks for your party with the items
The karma system is where this game really shines the most i think, i didnt really realise it during my first game so i kinda fucked my timeline, when i realised it was getting pretty bad (little shop-fox was getting sad) i had to reset and be more careful. So during the fights there is a nice balance between draining enemies to get a lot of exp but not going so far as to break them to not ruin the timeline, sometimes my attemps would be ruined by the fact that red's attacks also drain tho
Doing a "good" run is definitely the harder path, as often expected, i do wish there was a little something more to encourage you gameplay-wise, aside from the shop being cheaper and ofc the story, since you basically have more game content if you do a drain run
Doing a drain run really made me feel like a genocide route in undertale, you're a powerhouse, it's easier to win fights, but damn the universe is making you regret it, but despite that you are "rewarded" with tougher bosses and a hard final boss, then beaing the final boss is "great job you won, but you have nothing now"
Giving us cheats to have easier time experimenting and reaching other endings is extremely nice, i probably wouldnt have played so much without them.
The drain content is absolute peak, draining levels from enemies instead/in addition of hp, growing stronger (and thicker) in the process all in the objective or ascending your diety (who is also your lover) to godhood, aw DAMN that's hot. I also appreciate the game staying "suggestive" and not full on sexual, there's a definite lack of good "lewd" games out there, and this one is definitely one the best at that.
I do have some points of improvements i'd like to highlight:
Sam and Vix feel a bit "bland", especially Vix. Like visually they dont really have much more than "werewolf girl" and "leopard girl", at least Sam goes full muscle at high level, but Vix doesnt really have much "wow" effect to her being higher level, Red has some cool armor and magic, and most enemies have too (i used the drake and the snake as skins for all my games)
during the early game, some enemies combinaison are borderline unwinnable (at least if you go "good" route) with two healers being unkillable and two drainers quickly out-leveling you. It gets more manageable once you have some items with the shop, but early on it's hard
Structures feel a bit too tough, maybe it would be nice to have a skill/item that helps deal with them. a simple barricade can tank more dmg than a lvl 100 enemy, i often found myself skipping these fights.
Ascending Hizi is definitely a nice objective, but as mentionned before i feel like it doesnt reward you as much as doing a drain run, aside from the story (i did does hurt my soul to see her so sad in the drain route), but since you can still ascend her by going drain route, the incentive to be good is basically just "your gf will be sad"
The combat facing would definitely benefit from a way to make draining/healing animations faster, sorta like the bubble
i wish there was a secret ending for if you manage to drain/break the final megaboss, i did it after lots of farming, but unfortunately it just sends you back to the lobby cx
i probably forgot a few things, but it's probably enough, i'm not sure you'll read all this XD
tl;dr: peak game and peak concept, hope to see it grow and ascend as Hizi did
