Gameplay

The player controls one of four ship types: Type I, II, III, or Z. All ships share the same control scheme, but movement speed, option arrangement, and break gauge refill differ. Type Z was added for the updated World Ignition. Arrow keys move the craft. Button 1 releases rapid fire straight ahead from both the craft and its options. Button 2, when held, creates a circular field with a green border; enemies inside become locked on, shown by a blue line. One enemy can be locked onto multiple times, depending on its remaining health. When the ship reaches the maximum number of lock-ons (16 initially, more after power-ups or entering Break or Double Break mode), a chime plays and the blue lines turn red. Releasing Button 2 deploys homing lasers equal to the number of active lock-ons. Releasing many lasers in one lock-on grants a temporary score multiplier; the maximum possible multiplier is ×6.4, accessible only through Double Break Mode. Button 3's function depends on the Break Gauge status. In Original and Unlimited modes, using a bomb when the Break Mode gauge is full activates Break Mode, granting invincibility, increased firepower, and doubling the Break Rate counter's speed. Stacking one full gauge on another activates Double Break Mode, offering the highest firepower and score potential. Attacking multiple enemies quickly raises the Break Rate counter, which multiplies score from golden stars. The game has three difficulty levels: Simple, Original, and Unlimited.

Development and release

Yotsubane released two trial versions during development, plus a paid trial at Comiket 78. Schoolwork forced a delay from the original Comiket 78 release date. Version 0.10 had one stage and crude graphics and audio. Version 0.20 added three stages (Stage 3 boss unfinished) and the Unlimited difficulty, with only one stage available. Version 0.30, at Comiket 78, introduced the Double Break mechanic, three completed stages on Original, two on Unlimited, two on Simple, more shop items, and a second ship type. Version 1.00, at Comiket 79, included five stages and two sequential true last bosses for all difficulties, plus level practice and unlockable music. Version 1.01 added replay support and western-style score display, and fixed bugs including a scrolling bug that allowed duplication of the fifth boss and spawning of the second boss during the final boss fight. A screenshot on Yotsubane's blog shows a version labeled 0.40, but differences from 0.30 are unknown.
