I was looking for something quick to play last night and I actually found myself having to come back to this today. It was much longer than what I expected but it was worth it. Even minus all the smut the game is very engaging, which is something that's pretty hard to achieve in my opinion, but it's all for the best.
I will admit I felt kinda guilty skipping over all the sex scene text as writing seems to be your primary area of expertise but nonetheless I found the story captivating and seeing M10 through her mission and earning her a satisfying ending was enough to keep me going. Maybe that's actually a compliment, I don't know? It means you have a perfectly functional plot and that's a good thing to aspire for.
The combat was also definitely functional. Wasn't the most intricate web of mechanics and interactions I've ever had to untangle, but that's not really the point of the game, is it? Had the game on the strict level cap and Hard all the way and I did lose to Mimi once, but on the second time around better preparation is all it took (finished at level 8). I didn't find much use for a weapon other than the Hull Cleanser but maybe that's because I had already invested enough upgrades into it and getting more Bits was proving to be rather difficult.
As a final note, it would be nice being able to modify weapons without unequipping them. Sure, it's for immersion, but I think it's not worth the inconvenience of having to unequip the weapon, modify it, then equip it again considering the slight pauses the game does whenever you perform an action.
Other than that, the game does manage to pull off everything it wants to and I can say for sure those were some well-spent hours. Good job!
