Added thanks illustrations
To express my gratitude for your support since the release of the game, I have prepared a Thanks illustrations.
After the update, when you purchase first one of the in-app purchases or the Supporter Plan, a random Thanks illustration will be displayed.
If you’ve already purchased one or more, you can also view all the illustrations from the play data selection screen menu.
