Some compliments and critiques:
- The idea of matching babies to kids is an interesting twist on Papers, Please! and can really be taken into interesting directions--the genetics described aren't accurate to real life already (e.g. 50% on skintone and hair), so you could add some fantasy/biopunk stuff if you decided to expand on the concept.
- I love the extra creepy factor about placing children with parents. There's some reeeeeeally fun and messed up story stuff you can go with there if you develop this.
- I dislike the "light the baby you want to select" mechanic. I have a hard time matching skin tones when vastly different light levels are used. It's also harder to scan eye colors between babies and parents to compare them--even if something is obviously blue or green or brown, there's a recognition lag as the brain compares objects with different lighting.
- The order of genetic info you get has issues. Once I got bloodtype, I used it to select babies almost exclusively, because there's no 50/50 stuff like with hair and skin color.
- "Weight" and "height" feel kinda tacked on. I don't know normal baby weights and heights off hand, so if I want to use them, I have to compare them to all other babies to see if they're significantly different. It doesn't help that average heights and weights vary by country, so I don't know what constitutes tall or heavy for parents by the game's standard.
