I like the art, but there's so much bloom effect that I have to give it a 3. It's genuinely hard to see what part of the bar you're supposed to hit because the bloom blended all the colors together. The "blahbablahblah" sound effect when throwing again also got grating after a while, though it was pretty funny.
Otherwise it's a pretty good game! I think the concept's really hilarious, and I've always been a sucker for "throw thing and then it goes really far and upgrade it to go further" games. The subtle detail of "Oh I found this at the bottom of the ocean and I think you dropped it" was great!
Kudos on the solid entry!
