Idle game about fishing, it has an "ending" which is rare enough to be highlighted for an idle game. It took me a bit more of 80 hours but can probably be done quite faster if you know what you are doing.
It doesn't have offline mode which wasn't really a problem for me as I just put that one in the background while playing something else.
Pros:
- Game has an ending and all achievements can be earned relatively quickly for an idle game.
- Free
- Most game mechanics had a use at some point to make progress faster
Cons:
- Not a lot of depth compared to some other idle games
