I really like how you used the paper theming with this one. Having the enemies be drawn in and erased by the pencil is a cool visual feature, as is tracking the player's health through little scraps of paper. There's a lot of charming little touches that sell the concept. That said, while the game itself is pretty solid, there are a couple small tweaks you could make to make the experience a bit smoother. I think the biggest issue is that you can still get hit by the very small bullets.
