I eagerly accept questions so while I understand, you don't have to be shy!
I allow my sprites to be used in commercial games as long as they follow the rules.
Essentially, I just ask to be credited and for commercial games to not only offer my work as pay to use downloadable content. If you're selling your game and not the character by itself, this should be fine!
If I stumble upon the game, I might ask where the credit to me is if it's behind a paywall, so you can choose to tell me then or just tell me where it will be located beforehand. Either of those is fine.
And I always like supporting people who use my assets, so if you feel like it, please link your game here when it's done!
Good luck on your game!

That reply has helped me also, as I'm making a VN using your sprites as I am terrible at making VN sprites myself and I can't find a place to get or make VN sprites as they tend to either be really expensive or can lack in creativity and quality so I decided to come over here for sprites.
However, I do have this one plan to put a price on the game. I've made sure I follow all the rules, but I did find out it does say "please let me know in advance when making a paid game" which is my only concern. I will make it a free game if your not okay with me making money from the game.
