Great concept and fun early one, with 5 critical problems.
First, the pacing of the leveling system. I feel as I level up too fast, and quickly lost the ability to complete the quests.
Secondly, too many annoying ads, if you want ads put them every 4 or 5 minutes not everything a player goes to another map.
Another issue is the overpriced gear. The gear price increases rapidly and does not allow reasonable access to gear as you level, causing an inability to complete the quests and fish in new areas with new bait.
Also, the buildings in my opinion should give much more coins as you purchase better ones, and the camp can give me much more coins than the house if I collect all of the coins available. In addition the lakes are extremely overpriced.
Lastly the stamina and energy are just ridiculous. Don’t put a cap to how much a player can play a game and force them to wait.
A fix could be increasing the xp needed to advance, increasing the coins won for winning and fishing, and slicing the prices of gear.
