I Am Fish is a 3D platformer. As the name suggests, the title is dedicated to the adventures of sea creatures. There are several protagonists here. At the same time, the project is focused only on single playthrough. The gameplay is accompanied by believable physics. The gameplay is based on overcoming obstacles. Fish can swim, jump, and use special skills. Sometimes they need to get out onto land. At such moments, you need to get to water in another place as quickly as possible so that the character does not suffocate. If this happens, he will be resurrected at the last checkpoint.

There are 4 heroes available in I Am Fish:

• Goldfish – rolls over surfaces in a closed ball filled with water;
• Flying fish – can fly and soar in the air, spreading its fins;
• Pufferfish – can roll on the ground and grow in size;
• Piranha – has sharp teeth that allow it to cling to red objects or bite through them.

The plot plot here is as follows. Four friends lived quietly inside a pet store in a common aquarium. The idyll lasted until different people bought them and took them to their homes. The separated comrades found themselves in different parts of the city. They all decided to escape from their new owners, get to the ocean and reunite there. They will have to walk along rooftops, streets, sewers and other locations. On the way to the goal, the friends will swim in buckets, fountains, glasses, jugs and other containers. Character changes occur strictly according to the plot. Each of them has its own levels with different mechanics.
