Fun little incremental game, around 12 hours to complete game and 13 to get all achievments

This game must not be for everyone based on the reviews. But for me the graphics/art reminded me of a mobile game called "Hooked Inc." (I think that is what it's called) so I had a pretty good understanding of what I was getting into. Before we start, it is a fun game and I am glad I bought it. Maybe 6-8hrs of playtime (I just left it running in the background and played while waiting for queues. - it is a $3.99 game, It should probably be .99¢ as it is missing alot of features found on the "free" mobile game (maybe it isn't fair to compare them). - Although it is enjoyable it gets slow/boring quickly, your last fish caught feels identical to your first aside the addition of some automatic skills and a few more things going on. - The upgrade tree is also decent with tons of options, but again after an hour it is quite boring as there is no "choice" it is for the most part 1 direction following upgrades you can afford. BUT even if you had the money to go another direction it doesn't matter! all of the upgrades do the same thing. Would I buy it again? I would. Hopefully some updates come, with a bit of work it could be a very enjoyable game There are better games out there. Pro…

Wow that one was unnecessary grindy to the end. The pacing was good until like 2/3 of the game, then it became a grindfest. Still thumps up but maaaan you will grind...

A fun little fishing game that is relatively short, but very satisfying.
