Thanks for your submission ,I've seen this is your very first game so keep up! Here is my detailed feedback:
THEME 3\5
As other games, this is an acquarium sim, so not really fitting the theme
GAMEPLAY 3\5
Gameplay is smooth and very simple, but do what is planned to do. I would like some more fishes\shrimp species (meaby crabs?!?)
CREATIVITY AND ORIGINALITY 2\5
Not really nothing new or amazing, so I will just give a 2, sorry for that
VISUAL AND AUDIO 1\5
This is where the game really lack. No audio at all, UI is really basic and not very well polished, and graphic is clearly bad ai-maded. You could make more beutiful sprites for animals!
OVERALL EXPERIENCE 3\5
To be your first ever game, is not that bad! Keep up the work and this can become a great acquarium game! Good luck :)
