I like the roguelike idea and the games premise, I do wish the characters had a model other than a bean, and I feel like there's no "Loose" condition.
Theres is nothing stopping me from never getting the upgrades and just winning anyway, not that it's something that every game needs, but this game would benefit greatly if there was a loose condition like number of people drowned, exedra.
One last thing, why is my buoy still visible when I have grabbed someone? At first, I thought there was going to be an upgrade to grab multiple people, but alas I never got one.
