UnderGirl: Submission Path is now 25% OFF! Happy Holidays!Thank you everyone so much for your support this year.

So I promise to not back down. I have big plans for 2026, even though I work slowly and spend a lot of time on other things, mostly IRL problems. Still, next year you are all in for new games, manga, commissions, and more!!! I have so many ideas to share with you, but I won't rush. Your support means so much to me, I hope you'll spend your holidays wonderfully. Aaaand don't forget that UnderGirl: Submission Path is 25% OFF in the Steam Winter Sale right now!
