Pretty sure I gotten all the 99.99% of the fish and "fish"...
As a lover of pixel art games, this one is well done and interesting with its premise! Once you understand the mechanics of the treehuggers (and accepting that they may literally spawn on top of you), the game's difficulty drops significantly. It would definitely spice things up if there were more threats with different mechanics! But for what it is, this game is fantastic.
My only real issue is probably with the grind for the coins, but it does remind me of old flash games and getting paranoid over the treehuggers stealing my fish was quite... thrilling! Along with the fact treehuggers can spawn on top of you!
