Balloon Azuna

Balloon Azuna is a 2D platformer based on the story of a balloon girl named Azuna who must save her brother.

Azuna’s brother and his friends became interested in a secret military zone that was recently created in their town to conduct various experiments on military technology. However, due to carelessness, they entered the secret military zone through a hole in the wall. As a result, two of them were detained and taken into custody. They were thrown into a military prison for an indefinite period. The rest of the group managed to escape during the incident, and that is how Azuna learned about it.
