Been lurking for a while. Here's the non-demo version 1.4, and a version I modified for simpler controls and better balance:
ul.to/i82j42j8
Mod changes:
+ Alien H moves are a lot easier to pull off, once you know what they are. (Down, Up, AB is a move new to 1.4, but it's really position-dependent.)
+ Changed overall rhythm and pacing of fight. Heroine starts with more meter bars, which she uses to resist some (but not all) H moves. There's more variety and wearing down needed to get to the H moves this way. H moves also do a lot more damage now, while PG13 attacks do somewhat less damage. In addition, PG13 attacks build up the alien's gauge and lower the heroine's gauge. The alien can die somewhat more easily than before (drill attack can do 50% if you jump into it), but it's not super hard to win.
Not done yet:
- No AI tweaks. Alien AI does no H moves. Someone else will have to do this, because I didn't find it self-explanatory enough to wing it.
- Backbreaker rape seems to not be in this version of the game at all, as far as I can tell. Unless I'm missing something. It would take cutting and pasting from the other version in order to implement it here, afaik
- Heroine AI health bar seems to blank out if you don't hit her for a while. This seems to be new to 1.4. I don't know what was done to make it like that, but it's lame. I could only figure out how to give her a tiny persistent health bar under her feet. :-/
