Did not work on Android I'm sorry to say. Extracted and ran fine, but no images appeared and the text was so small it needed much zooming to read, while a massive error patch where I assume an image should be took up the page. Would benefit from some screen-relativity css (mobiles are a total ass to code for)
Going to play this on PC next to see what I'm missing. Hope to update this in a bit :)
EDIT: There we go. PC ran it fine (even a poor potato)
I like it! It's a nice simple interface, but could be improved with an auto progression if you had a need (heh) to go through MANY pregnancies... perhaps some kind of 10X click for the ultra-lazy.
Pre-suggestions (Actually implementable)
More pregnancy stages
Expression changes
Changes in hand/arm pose
Speech-bubble (Let us write our own trash for her to say)
progress scene alterations (pictures on the walls, tattoos of assumed baby-names etc)
Click BACK. Hold a key to reverse when clicked or something
Insane over-the-top Suggestions:
Currency. Surrogating for certain families or businesses to get you money. Cam-shows for the perv... err... i mean... Interested... Then things to spend said currency on. Vitamins to help the baby grow bigger, increase a chance of twins, triplets etc. Increase milk (anyone else wanna shout 'boobies' here?) and of course, upgrades to social status and setting that will unlock even more opportunities to exponentially increase both income and waistline. want to set up a lucrative breast-milk business? I'm sure there's plenty who will pay (even if there aren't, it's a game!)
Weight gain. Not quite my thing, but it happens and is a big-ticket item for many viewers. Bigger butt, thighs, boobs and bellies can't all be bad? Currency would help here.
Level her up! Instead (or as well as) money, why not breed points? Upgrade her fertility as well as her fecundity. Cash for Points in a science lab happy to breed you with... err... whatever the green wiggly thing behind the pipes is.
Mega Pregga. Twins, Triplets and nonuplets... But only through money or 'breed-point' upgrades. More milk. Wider hips to reduce that after-breeding cooldown.
Life simulator? Ok, I think I'd get bored of this, but it's a logical progression. Between breedings, keep her going and make more money to get more food to make more babies to make more... you get the idea... plus, improve her home for comfort and profit!
Teh Sex! How ELSE do you get pregnant? Special sex scenes for breeding special, hard to find or just fun characters. Scientist with a tentacle monster? Score of horny guys from a bar? Some blind dude with a turkey baster? Why not! One-off scenes to use in a gallery, plus re-visit benefits of 'she'd look better preggers... MORE!
Customisation. Of course, everyone has a preference right? I found that I could never nail it in one... so let 'em chose! They want her with tattoos, half shaved head and a hair colour only seen in acid trips? Let em! Maybe unlock it via DNA/breed points or whatever.
Dressup. Dang, look at me making all the extra work (don't worry. I do this to myself too...) but how good would she look in a barely-fitting shirt that used to fit a hundred clicks ago? buttons straining, stretching then eventually popping. A tee that rides up until it just won't stay down anymore. Whip out the maternity lingerie for the bonus points of holding in that lovely milky rack for a few more clicks...
Ok... I'll stop now. (disclaimer: These are suggestions much in the same way you might see things written on a bathroom stall. Do not feel obligated to stretch to ANY of these as I know from experience just how exponential ANY of these changes will be)
