I love this game I really do but when I got to the final boss it kind of sank a bit, along the way the bosses got harder and that's obvious to why but when you get to the final boss you basically have all your upgrades and she really isn't hard to beat along with attacks being slow and the main threat is just her being tanky and the arena itself except if you just dash the obvious laser and energy sphere.  The way I'd see her getting any form of buff would possibly be a new attack and to speed her up because unless you're doing upgradless, she takes around a minute to kill with maxed out leg strength and you wouldn't even need any upgrades in gun, health, or regen (also the girls on the side can't attack you if you're in the middle of the stage).  Compared to the Angel and Werewolf who was at least a little hard to hit since you had to keep jumping and shooting and dodging when they started chasing you and put you in a grab.  I was kind of hoping for an animation with her that being anything or something with the girls in the tanks but no. I would love to see at least something get added with her and the girl with the Angel and Final Boss fight on the... Meat Pillar..? Not sure what it is but I think she could make for an easy scene. Would love to see a futanari alternate version of the boss depending on your Dick EXP or just maybe a setting as well. (Also what was the point of the girls in the tank, they just climbed into her tits and that was it, it felt more like just time to attack the boss if anything. (I saw what it was, it was just a minuscular heal.  The health she healed was basically worth a no upgrade kick and should probably get a buff)) Anyways I'll stop my selfish ramblings about what I'd like to see in the game, if you continue development to add new stuff for some reason, I can't wait to see it, keep up the good work! (One last thing, Metal needs a drop buff, take some % out of wood drop and put it into metal, after breaking every box in the game and killing tons of enemies, getting to the end I was still starved for Metal and was thriving on wood, could have just been my RNG but yea.  Anyways great game!)

Final boss really hit you with the wait, holy shit what do I do now? I do agree there's some rework to be done to make it flow better with the game. I've found that the defensive weapons like energy balls, fields, and even the girls shooting cum don't really play in any sort of manner. Kinda random or roughly positionally based.  I don't believe the boss needs to be difficult, but rather keep you running back and forth since the map is so big. Plus the boss has double the "tanking" ability.

It would be nice to see those orb things go away for this boss, and the succubus' who casts them. I feel other defenses or enemies would tie better with the boss.  The two girls on the side with the parasite dicks should be constantly releasing cum which forces you to run  but, you could sabotage them and shut them down for some time if you have sex with them (taking a parasite charge and health damage so it's a trade off but fun interactable). 

I also see how you believe the tube girls don't serve a purpose. I think if this mechanic is used you should be able to grapple them (not shoot) and stop them somehow. If you don't and they reach the boss and get absorbed then her health should be greatly healed by say 25% which makes you have to deal with them.

For the enemy spawners, I'm not sure how the succubus ladies play into the boss or even the story and they seemingly would be better replaced by other parasite controlled enemies. I would think any would do like the various parasite girls, or one that drops parasite eggs (kinda like the angel but not her). These would rotate and spawn on random chance making you change your play style slightly through the battle.

The boss should also have a breast phase attack. I'm thinking it replaces the laser beam that goes back and forth and she could either milk her self releasing a milk wave that forces you to the sides. Maybe, she gets a grapple move and forces you to sex her breast and if you cum you heal the boss similar to the tube girls.

My 2 cents on the final boss. But also enjoyed the game a lot as well.
