Really, really fun game. I like the name, I like the pen-and-paper aesthetic and especially love the level design. While simple, I think you've managed to design ten different levels with their own ideas and mechanics. It was a really cool curveball that some of the levels (especially the ninth, of course) turn into multi-screen, almost adventure levels. Impressive how you managed to make this under the time constraints of the gamejam! The slow motion mechanic is another super fun touch. How it makes seemingly impossible levels solvable is very clever.
I don't really see how the game suits the theme, though. You write that the player must choose between two power-ups, but I can't think of how that actually connects to 'saving' anything, let alone not saving 'them all'. On that note, the choice of power up, at least in my route, didn't influence the gameplay greatly. I could 100% be wrong about this, I only played the game through once in its entirety.
The sound and music are fine, but not too engaging. All in all a really fun game, I had a great time playing it!
