Press "D," "→," "␣," or click the screen to go to the next picture, and press "←" or "A" to go back. Enjoy!
This is probably my simplest project, as it only consists of two blocks and one sprite. The original pictures are higher quality than the shown media, because scratch, unfortunately, uploads pictures into bitmap, which downgrades the quality (this is somewhat fixable with you-know-what, but I use Safari). These pictures are originals shot from a GoPro Hero 12 Black with original lens, and no accessories.
