>>33469151Cool idea! Some things to pay attention to:
• Some trainers face left or right and can see N tiles ahead. Make sure that none of them can notice you from offscreen.
• If you shift the screen over by 8px, the side columns of tiles will be cut in half. Check what happens to NPCs standing there. It might be weird.
• Walk on the leftmost edge of maps and make sure their border block doesn't bleed through in odd places. (A canon example: walking into Cerulean Cave, the border block of trees bleeds through at the top of the screen.)
