Deep Deep Ocean brings me a great game experience with all the tile sets and min-games. The general blue theme helps me to immerse myself into the deep sea feeling, which feels like I am in the deep ocean right now as a fish (or a human).
The color of this game is generally blue with important characters or objects being yellow. The blue color corresponds to the ocean elements in the natural world, which helps to render to a similar environment. The wave animation, the sun in the sky, and the screen movement from top to down also implies that we are in the ocean and we are exploring from the surface to the deep ocean. Personally, I really like all the characters being yellow instead of other colors, because it allows me to know what I can interact with in the game and what to expect next.
However, the entries in the game are not explicitly labeled in the game. The three entries are at different tubes in the second scene, which corresponds to different parts of the tubes in the bottom right of the screen. I was confused at first about how to enter the other games when I found the first bubble game. But after a few rounds of talking with sprites in the game and wandering, I found the pattern and correctly entered the next two games.
The first exit of the game is actually mandatory and instructional, since there is only one way you can move and you can only move horizontally. After I move to the right most area of the first scene, the transition begins. However, it is not two separate rooms. The rooms are connected together since the camera only moves down instead of being black. The other exits in the game are not explicit, and it is only mentioned in the text messages after players interact with the essential sprites, which is different parts of the tubes in the bottom right of the screen.
The text messages are the core of the game, since it provides the essential information and instructions to players. Without talking to the sprites, players will not what to do next. Also, the text messages act like an inventory so that you can see what you gain and what you lose after each conversation. For example, when I talk to the crab, the text message can show me that I have gained a shrimp and I can do something about it. It also works for the starfish, which can give me the coupon as the entry requirements to the game.
The three mini games are also wonderful experience to me. The first one that I encounter is to collect all the bubbles, and the second one is the maze. The final one is actually the most interesting since I did not actually play the game, but I managed to get out of the room because I talked to the sprites one more time.
