I'll give my verdict on things so far. Alt + enter to make the game fullscreen by the way.
Pros:
-First level's difficulty has been overall toned down.
-Protag now has a hp bar rather than only taking one hit before dying.
-Protag's animations are a fair bit smoother than before.
-Snake girl and Zangief bull girl have better scenes.
-Zangief bull girl fights a bit differently but overall has a clearer pattern.
-Girls can now H you without you dying... although you still have to die to get their full scene.
-Apples to increase hp and reduce lust (the pink bar) appear fairly often.
Cons:
-Some of the protag's animations have lost the personality they had before. The running animation lost its King Arthur vibes and became a sunday jog.
-Protag wields a sword yet throws full-sized rifles for some reason.
-Mushroom girls seem a bit dumber than before. They won't jump over obstacles after you.
-The new music choice doesn't really fit... why'd he change it?
-No new weapon types. Gotta wait for those to be redone again.

-Feels a bit two steps forward and one step back since the second level was complete before DHM did the big remake.
