What an utter delight of a game! I really enjoy when a game rewards both meticulous and casual gaming. The game has plenty of opportunities to try and maximize your profits, but easy mechanics to let you just buy whatever is below average cost and sell whatever is above average.
I was actually about to try and grind out the last 5 fishables, but the game crashed. There's a good chance that's a PC issue, but I thought it was worth mentioning for both game function and enjoyability!
