Thank you so much <3. For the artistic part, the process is actually quite simple: I created the collages rather roughly using Photopea (making heavy use of the Healing Brush), then I used ditherit for the "pixelated effect" with a 14-color palette (to use 14 colors + White and Black). For the characters, I used the same process but only with black and white.
I took a look at the canvases, and you're absolutely right. I’ve now tried changing all the dialogue canvases from on click to on release, and it does seem like the text flows more smoothly. Thanks!
