I always appreciate game jam games with stories, and this was told quite well, although I'm not exactly sure what happened in the ending. The gameplay itself is simple, but its fun dodging hazards and enemies, especially in the boss fight.
I actually didn't realise I was taking damage in said fight until I died (the rest of the game has you dead in one hit and I was focused on the middle of the screen). But that barely even matters because you lose so little progress. The checkpoints really help with the occasional times I'd get hit by obstacles on the edges of the page in general. Overall, an incredibly good entry!
