Hello! I enjoyed playing your game, the mechanic is really addictive, I really like the gameloop & all of the upgrades. One small suggestion is that you make it so that the hook can pick up multiple bits of cargo at once. This would make the depth upgrade feel a bit more satisfying, because you could start to collect more quickly.
Good job on balancing all of the upgrades! It was satisfying to play through the game and continually improve.
