Nice and simple platformer that transports me to when I was four years old and played Super Mario Land the first time on the Game Boy.
Felt the level design and enemy logic was reasonably challenging, and really appreciated the save-of-progress of leaving previous enemy spawners destroyed after the player dies (otherwise, it would've been too unforgiving; there are some points where the player is swarmed!). Also hadn't realized about the shoot function until some time in when I realized there must've been something in order to get past / destroy the spawners. But once I figured it all out, it was a fun playthrough trying to get to the top.
All-in-all, a very functional game with nice pixel art fitting within the theme of the jam. Good work, devs!
