Congrats on the release, the game was really nice. We're starved for breast expansion games, especially for ones that are not just visual novels. Love the art both in this one and the other upcoming project, I just would have liked to see more art as in the portrait pictures. If you plan to open a patreon I'll surely subscribe!
Yes! Just to throw some ideas: voting on the next scene/theme that gets added, accessing preview arts and early builds; the highest paying tier could allow to choose a character/scene that gets added once per person. If you create a game discord you could lock some channels behind the patreon subscription and post some of the perks there and also stream some of the art process from time to time.
