Welp, I've checked off all the new forms. The next update seems to have a few new forms to grab though, so that one might take some more time.
Side note: Please keep updating the walkthrough where it's possible to view the upcoming update ahead of time. While it could be seen as spoilers, it does keep people like me invested in knowing what is going to come next.
Extra note: I hope the version posted here will always be free even when the game is finished.
