This looks great. I am excited to play the OG game, but I am really excited for this remake and/or continuation hopefully someday. Both Dipper and Mabel and the general art here look great. And I like the personalized dialogue boxes for both Dipper and Mabel here, and it would be cool to see them even more spruced if possible, to show even more of Mabel and Dipper's character.
I checked out your other Gravity Falls game, Mystery of Love, and that games looks great too, and I am excited for more of it and/or the full game someday.
It would be cool if Dipper, Mabel, Pacifica, Soos (because he is with Melody), and Wendy had like friendship routes or something too, but I know that would probably be a lot, and the 4 routes (Stan, Ford, Fiddleford, and Bill, which is great) that you are already working on in that game is already cool and a lot. Hopefully Dipper, Mabel, Pacifica, Soos and Wendy, still have some fun focus in that (Mystery of Love) game, and/or get a lot of good focus in this game (both the OG back to summer and the hopeful remake and/or continuation of it). At least Mabel and Dipper seem to be getting good focus, which is great.
Anyways, excited to have found you, and to have found some more Gravity Falls stuff. Hope to see more GF stuff (your Mystery of Summer and Back to Summer OG and remake/continuation games, and etc.) someday. ^_^
