Man there's something so satisfying about a nicely designed clicker game. This one really scratched that itch for me in a great way. The upgrades were noticeable, the clicking solid, progression felt reasonable. I think some music would have really made this sing, as well as some kind of feedback from the animals as I'm clicking them. Adding a little bounciness or motion in there (other than the bubbles popping out) would really add a nice tactile feel to the game. Overall, pretty great stuff!
