It's more of a screensaver than a game. If you are looking for a incremental game that you can "engage" with for progress and completionism this isnt for you. Buy fish, turn game off, come back tomorrow, sell fish, buy new fish/upgrades, repeat. There's no tech tree here, no +$ sale value multiplier for fish, no "complete the set" bonuses. Its a really chill aquarium that you can name your fish and decorate/customise. Not much of a game but I dont think its trying to be.

Letting the XP per feed increase with like an e18 purchase that doubles it again would be nice when the last thing needed is waiting days or leaving your phone idle for hours pressing and holding in a corner to help fish grow faster... But being able to 100% it after coming back to it in a week isn't horrible either for a nice 20 hours over 3 weeks to 100% it.

genuinely love this game. its is a very slow paced game. something you can pick up and put down at your own leisure. admittedly, there isn't much to do. i don't mind the waiting. it gives me something to look forward to. the insane amount of fish to collect makes it worth it. it could be a little more balanced in terms of in game costs. they get very high very quickly. I enjoy it regardless. I'd love to see a minigame or two added to give a little more to do.
