Following launch, the developer shipped a series of maintenance updates: a feature patch on January 22, 2026 (adding a weapon selection priority system), bug fixes on January 21 and February 2, 2026, and a performance/input optimization update on March 17, 2026. The most recent developer communication was on March 17, 2026. No DLC has been listed on the store, no future content has been announced, and the developer has made no statement about additional content being planned. The game's post-launch activity has consisted entirely of maintenance and bug-fix patches — there is no pattern of major content updates. With today's date being July 23, 2026, more than six months have passed since launch and over four months since the last developer post, with no signals of upcoming content. The game appears to have launched as a complete, self-contained product.

About this game

A homeland defense adventure to raise and fight kawaii annihilation weapons!

Handheld annihilation weapons to defeat invading enemies

Hold MOCHI-O in your right hand, aim at the enemy, and attack. Enemies you defeat will drop seeds.

As you accumulate experience gained from picking up the seeds, you will gain skills from random choices.

Strengthen your MOCHI-O in battle to destroy the approaching enemies and defend the defense line.

Throwing Seeds to Breed MOCHI-O

Spend the money you earn in battle to strengthen MOCHI-O.

You can also unlock weapons, which will give you an advantage in battle.

Giving seeds to MOCHI-O will increase its trust level and strengthen its status.

What is MOCHI-O?

A cute hamster......but a handy annihilation weapon for homeland defense.

The player's mission is to raise MOCHI-O as a keeper and protect his country from foreign enemies.

The heartwarming dialogue between the characters is also a highlight of the game.

[Creator's comment]

Wouldn't it be great if you could go on a rampage with a small, cute, and extremely strong character?

That's what I had in mind when I created this game from start to finish.

I would be happy if you could go on a rampage with a small, cute, and extremely strong character.
