Daily Reward bug

Hello! I am here to report a bug in the daily rewards quest. When you receive the quest, it forces you to do it when you get it. I didn’t find this as much of a problem, until when I click on the shop and bonus tabs and find that I can’t scroll. It also keeps telling me to click on the bonuses tab after I already did. Please fix this issue, as I have tried uninstalling and reinstalling, and nothing seems to work. You can’t control your sub, you can’t upgrade, and even after running out of oxygen it still doesn’t work. I would love to keep playing, but this bug makes it impossible.

Good idea bad execution

I like the idea of having a submarine and exploring a post apocalyptic ocean, but I just feel like it’s should be a full priced game that you pay for up front instead of the needless amount of micro transactions
In this game. A very large amount of the screen if covered with menus that take up way to much space. This being a free to play micro transaction festival of course has to have a “spin the wheel for a prize” game in which it works like any other game of this form, but after you spin it it will have a little notification in the menu that takes you the wheel. The thing is once you press the spin button you instantly get bombarded with an ad. This wouldn’t bother me so much if the in game store was bearable. There is this mechanic where you collect resources and sell them for coins. It sounds great but there is a sell all button which seems nice, but no it kicks you straight to the membership store and asks you to buy a membership to sell all of your stuff at once. Remove membership and clean the screen a bit and you might have yourself a pretty decent game.

Could be fun

This has all of the essentials of a would-be great idle adventure. HOWEVER, eventually you start collecting six or more varieties of resource, call them gems, but can only hold a finite amount of those gems. To upgrade the amount you can hold, you need to collect, say, 200k of two of those six resources. But if you get too many of one of the resources you won’t be able to hold enough of another resource that you need. The solution? You need to sell the resources that are overburdening your storage hold (which you probably need to upgrade that hold). Surely you can just sell a few to make room, right? Nope! You must sell them all (of that particular resource) and start over.

So if you decide to go truly idle at any point, you wind up with too many of one resource and have to start over for no logical reason. There is an easy fix: the ability to sell some, but not all, of any given resource. Without that fix, the game just feels counter-intuitive, not very fun, and certainly not an idle.
