Really cool entry. I was hoping someone would make a "roguelike" twist with upgrades and procedural maps, and I wasn't disappointed. I like that even though the levels are procedural, you have the classic "clear the map" gameplay once you find the whirlpool. Felt pretty well balanced to me, too. Challenging enough to make me feel good for beating it, but not so hard to make it feel unfair. Though maybe it would be cool to make the upgrades a little more impactful to encourage getting more dots.
Either way, I had a lot of fun playing it, and that's what counts. Great job!
