Yup! It's not high on the priority right now, I want to get at least past the mid-game (3 more ecosystems) before I worry about it. There are 2 ways I could implemented:
- Current best: the gallery is unlocked upon beating the final boss, and remains unlocked for NG+
- Pros: big reward for finishing the game, centralized, permanent.
- Cons: not available for first playthough.
- Not-so-good alternative: the gallery for each ecosystem is unlocked after 100%-ing that ecosystem.
- Pros: available during first playthrough.
- Cons: fragmented, locks lewds behind finding jewels instead of tentacles.
Your comment does raise an interesting point, and something that I should actually add is a lewd counter, that tells players if they met all tentacles in the current version. I used to have a message in the intro that said "there are X tentacles to find" but I got rid of it because it looked awful. I will see if I can include a functional "counter" of sorts that shows up in the pause screen or in the collection.
