Fun little game! The mechanic is cool, and you did a good job designing for it. I love how the music (even with a little rewind sound!) fits the vibe so well, although the weird little Gremlin-looking enemy sprites feel out of place with that vibe.
It seemed a little unforgiving for me personally, especially because it pushed you back to the beginning with every death. But I'm pretty terrible at games in general, so it's possible that's just my fault. Checkpoints or something like that might be nice if you had plans to expand.
Overall, good work! It's a cool mechanic and you've made it fit the theme really well. I love the little UI tape with the pencil animation.
