Hello, lovely sim game you got there, very excited to try it.
I enjoyed feeding the fish and collecting them, I was not able to experience most of the background customization because they were behind paywall correct? I did find the need to see more visual hints in the customization of the tank area, it would help me to understand the options more. Maybe have some mild, easy going cleaning tasks, then follow up with upgrades to get a tank cleaning fish if it's not already there, that would be fun too. Other than that, lovely game I can see this as a great companion on desktop to distress, beautifully done.
