Description by Suwitcha Sugthana Written by the developer, not by AppBrain. Click to read.
Description:
I.S.U.D. Zero is a portrait bullet-hell boss rush built around clean reads, a tiny fair hitbox, and fast retry mastery.
Enter the simulation chamber, learn each boss pattern, graze close calls to charge Phase Pulse, and chase cleaner clears across The Instructor, Mirror Cadet, Twin Array, and The Cartographer. Every run is short, sharp, and score-driven.
Bosses move, mutate, and escalate through multiple phases. The ship only takes damage at the red core, so the chaos stays readable even when the screen blooms with bullets.
Features:
- Precision drag controls for portrait play
- Fair red-core hitbox with optional callout
- Graze scoring and Phase Pulse screen clears
- Four multi-phase bosses with distinct patterns and visual escalation
- Five additional boss slots marked Coming Soon
- Difficulty options, persistent best scores, and ranks
- Game Center weekly and all-time high score leaderboards
- Neon arcade presentation with original audio hooks
