after 34 hours ..... I can say I want to like the game but. the leveling is off balance between AI and the real player. it seems once you hit level 50 every fish attacks you. the clam power ups could use a buff or more time sometimes you dont find any other fish. leveling a fish to level 39 takes for ever! the coin buffs need to be buffed its like you put in all this work and get a .5% buff( basically nothing) id like to see at least 1.5% for each coin 3% would be even better!!!!

I like the game but also hate the game. you work to level up and then fish 10 levels above you spawn in. you have no sense of accomplishment, you're always low level. even paying to get rid of ads and using bonuses to grow fast are made useless. also the species that you play as becomes very abundant, and they steal kills and food that you faught for. very annoying when its a rare fish and you need to unlock it but it gets swarmed by others of your same species, right before you finish.

I like the game, but I choose to not watch an advertisement to respawn and it makes me watch one anyway to go back to the main screen. Even switching which fish I use pops up an advertisement. It forces you to watch advertisements for a longer period of time then you actually get to play the game. It's ridiculous and makes it impossible to have any fun. I will leave it installed for a little while and check later if it's fixed, but if not just going to trash it.
