Newest update: Phone Edition (2026-09-30)
- Moon Sakura now plays on phones: the whole arena fits a tall screen, a compact top bar shows lives, bombs, score and graze, a stick with FOCUS and BOMB buttons, a one-column shrine menu, and the spell editor split into LEVEL / GUNS / WATCH tabs.
Earlier update: Arena Stability (2026-09-30)
- Battles no longer crash when you enter a fight.
- The battle arena rebuilds itself if it ever goes missing — no more invisible walls trapping you mid-combat.

@sunraku · 2026-09-30 · played 13 min: “Really nice game bro! The concept is nice since you combine Anime + the shooting game genre. It would be much more good if you put dropping power ups haha”
@vladtheimpaler · 2026-09-30 · played 4 min: “Brother, the game reminds me of an old game and it really has a special place in my heart. I gotta tell you that level 1 is very very very hard hahahaha”
@yujiro · 2026-09-30 · played 6 min: “The graphics are really cool, and I had fun shooting and dodging enemy projectiles. I’m just wondering why we’re playing as a girl hahaha, since I’m used to spaceship characters.”
