Pictures changing according to the girl stats is really awesome because we don't know exactly what to expect when we perform an action. When a different picture comes, it's a surprise and this makes me go further and further to see another things like this. You mentioned that there is a secret inside the game that is undiscovered yet. Keep going on this secrets haha' it's very fun when there is something to discover. I saw someone on discord that write a review, if you don't mind, I'd like to do the same on future builds. (Sorry if I made some ortographyc mistakes, I don't know where I can use "in", "on" or "at" -_- / portuguese is better than english for me :D )
Edit: oh and if, in the future of the game, you want someone to translate it to brazilian portuguese, here I am ;)
