Thanks so much for the detailed feedback! Yeah, there's issues with UX with the colors of puzzles and back button animation, eughhh... When the judging period's over, I definitely plan to fix pretty much all those issues with juicier UI and nice transitions between scenes and fixing up the puzzles so they have more color contrast.
For clicking through the text, are you referring to how slow he speaks and that you want to click the text so he finishes his line immediately? Bob only has one line of text for every page, so clicking through the text wouldn't do anything otherwise lol
I wasn't sure if we should have added an eraser-like function since that wouldn't be very paint-like... but Picross games usually let you reset the board. Maybe a clear paint color in a bucket would be a good compromise?
