Tbh I love the graphics and I'm surprised this was all made from wallpaper images. The story is well told with the help of those images and I have to say your skill to use those images as graphics took me off-guard.
I only wished there was an option to skip the cutscene / explanations, because I personally think that when you are playing a jam game, you usually want to try the content asap and then, if you are interested, keep playing until 100%, same goes with the help menu, which I think should let you proceed + show all info you need to know at the same time so you don't have to wait if you finished reading / be frustrated because you didn't have time to read everything.
Still, I really enjoy the concept and even if you didn't make the graphics, I really like how you implemented them into your game. Hope to see more of you in the future ;)
