Ok for real yo, the levels of grind in this game is making me nope the fuck out.
To the dev:
There's some serious potential in your work but it also sucks major ass. I'm sorry but it's the truth.
You don't respect the player's time and that pisses me off. If you want players to put in some effort to see your lewds, fine, but you've taken it to an ungodly extreme.
If you want a time wasting gameplay loop in your game, it needs to be skill based to feel like fun and not as a punishment. Preferably it also needs to have a high skill ceiling. The time wasting "gameplay" you've created (with the mining and the crafting) is just me pressing a series of buttons in the same order over and over again. It feels like filling a bucket using a teaspoon. It's boring as hell and I can't take any more of it.
Furthermore: crafting for crafting's sake does not a game make. Crafting items can be fulfilling if they are used in another gameplay element but the only use of items in this game are just as hurdles to advancing the story. It's basically the same as "fetch quests". Boring.
This monster you've created is making me feel like an accountant and it's the exact opposite of fun. Nobody can like this. I might be able to suffer through some tedious shit for some lewds and I've done so on multiple occations but this time I'm tapping out. It's definitely too much.
It's so so sad to see this because the rest of the quality of the art and coding is very very high. I hope you can get your shit together because I'd like to play through your game to see the rest of it. But not like this.
