Hi,
the most annoying bugs I found in 0.04 - standalone are when the pregnancy/infestation gets higher value than 4. That happens when MC has intercourse with the enemy for too long. Than MC gets stuck in getting up animation loop that cannot be broken unless you use CheatEngine to lover that value below 4. Than that loop ends and birth scene plays normally.
(This may be partially connected) I'm not sure if I read the code correctly but I saw limit for interaction to play max 3 times in row. But with to high stats, this scenes play more than that, like 10+.
And when MC is attacked by worm after that scene is finished and she is getting up her face sprite is offset in comparison to rest of her body. (this one was present in 0.01 too)
I thing that is all I found for now. Thus far game looks good, keep it up.
Good wind
