I have three things to say

1. What if the female characters in Tacarau remain naked?

2. Will a female main character be used

3. What if you make another game with only naked women without any clothing, set on an island or forest?

Hey your project looks very cool and I think it has great potential, nice work! I have some suggestions that might interest you:

• I think the progression on the adult content is too fast right now, it would be nice if the player earns rewards (scenes or events) by gameplay elements.
• More survival elements: now hear me out… I know this might sound a little too ambitious, but your kind of game will highly benefit for rudimentary survival mechanics, such as thirst, collecting resources, crafting and building, obviously will be very simple but there are ways to make them fun instead of chores.

On the topic of the survival gameplay, I highly suggest you check out a little old game called “Stranded II” by Unreal Software, the game is very simple with hunger, thirst and rudimentary building mechanics but is very fun, hence the reason why still have a modding community.

Anyways best of luck with your project.

A magical contract with monsters and magical spirits, I think you know what its content is 

Of course, you should make Dem contract with the Petagonia. This is the name of the monster or something like that
