DUDE I LOVE THIS GAME!
I really like this mechanic of min-maxing and taking risk how many competitors you should eliminate before the egg.
I made it to the end but had two rival sperms so that's why I failed.... But still the music tension at the end is amazing!!!
You got the theme, you have really good mechanic and I will for sure return to this game! Congrats really cool game :D
Shameless plug I also made similiar "sexual game": https://rokkos.itch.io/keep-it-in-your-pants, so I really appreciate your creation!
