Parasite Infection

This is the story of Chet, a normal guy who is abducted by aliens and infested with parasites.

Parasite Infection Progress Update:

- Massive codebase revision.  Unifying a bunch of modules from part 1 and 2 together.  I think this will also help clean up a lot of bugs.  Should be done in 2-5 days.


Progress Outline:

- Develop plot outline (completed a while ago)

- Develop list of specific core features (completed recently for part 1, 2, and 3)

- Refine core features <- I am here

- Refine plot

- Refine artwork (may take a while, always being worked on but it is slow)

- Final bug check

- Change numbering system to "Parasite Infection Part 1" etc. for final release


I'd just like to say - I've definitely internalized the phrase "it's going to get worse before it gets better".  Evolution is messy.

Stuck on the chapter with your family and the house.  What objectives do you need to complete to advance?  Had two or so infections on the family and teacher, seemed to be stuck in an endless grind.

This game is in a weird spot right now with the recent updates, which have removed chunks of the game and added a lot of placeholder content and stats. If you've never played this before and want a more complete game, I'd honestly recommend a version before 2.31. The writing's fantastic and I appreciate having a breadth of things to do(even if they get a bit grindy), and 2.31 doesn't change that, but enough's changed that I can't recommend this version to newcomers.

The addition of alternate paths in the first part is an interesting idea, but it also makes it easy to miss a lot of content depending on which path you take. It also seems unbalanced, since certain paths let you start the next part with tons of parasites on hand already & many transformations already in place.

Part 2 has a few QOL improvements(no more tediously clicking the same paths through your house every day), but it's become considerably less clear what the player is meant to do and what their goal is. Although this might be because of the drastic changes to part 3, with a new plot that seems like a non-sequitur when added to the existing part 2 content. The new part 3 is also blatantly unfinished, limiting you to doing the same few actions in an endless loop.

The player's part 2 stats have changed, and none of them seem to have any function yet. In fact, none of them seem to change at all except 'force' and 'mental pressure'(which is a holdover from Part 1 that appears to cap out at 20 in Part 2, although it might be a bug since it wasn't a part 2 stat in previous versions).

Speaking of bugs, there's a handful. The male start has gone from the initial parasite infecting your rectum to claiming it infects your vagina(although later status shows it's in the rectum as you'd expect). Putting the choker parasite on in part 2 and submitting to it sets your attraction to Joan instead of your parasite master. Entering vacant rooms while visibly changed somehow alerts the owner that you're infected. You still have a penis(regular penis, not a parasite one) in the masturbation menus after becoming fully feminized.

I don't mind the writer changing up the game for whatever reason, but this update feels not even half-finished.

The changes to 'part 2' were unneeded and completely unwelcome. It was fine as it was before. And well the complete change after it was just ugh.

Enjoying this game a lot please keep up the good work

Just a note for the current release, when starting as a male the 5th screen into the game (when originally infected) the parasite should climb up into the host's rectum not vagina (Because males don't have a vagina). Minor editing changes needed.
