✨ Introduction ①: What is “HOSHIOMIO -Stella Attacks-”?

The protagonist of this game is a single white cat. The player controls the cat and observes the starry sky from its perspective. The controls use just two buttons: “Cat Punch (A)” and “Look at the Stars (B)”. Steam post image Steam post image

The “stars” floating in the night sky are actually unidentified flying objects that fall toward the cat’s location. The key to countering this threat is a ball called “Minon.”

Minons of the same color can be combined, and their shapes can then be used to craft a variety of items.

There are over 50 different shape-and-crafting combinations. From interception weapons and defensive walls to landing prediction analyzers, a wide range of tools for both offense and defense can be obtained. However, all of these combinations must be discovered by the player.

✨Introduction ②: “A Sense of Wonder Born from a Sea of Assets”

One of this game’s defining features is its extensive use of assets sourced from the asset store. Those “familiar assets” that Unity creators have likely seen at least once appear in a full-fledged sci-fi story, delivering an intense battle drama between living beings and the stars.

✨ Introduction ③: “Is This Game Hiding Something?”

Recorder footage of the cat in battle suggests that numerous mysterious games exist. These are currently under investigation by our research team.
