Citing the game's home page,
The "bullet hell" seems, as far as I played, relatively easy (usually low density) but relentless, offering more intense action and less absurd tight spots than typical CAVE style.This is a bullet-hell shooter.
Hold down the X key to activate hyper.
Everything except you will slow down.
If you defeat an enemy during hyper, the enemy bullets will disappear.
Try to defeat 4 stage + the last boss.
The "hyper" is a slow-motion mode in which bullets and enemies are almost still and bullets from killed enemies become gold score items. Outside hyper mode, enemies drop green energy items that are spent to activate hyper.
No powerups, no bombs, abundant score-based extends that make scoring a priority for survival and completion.
Brilliantly, hyper mode can be used very freely (it's instantaneous and without gauge-filling activation thresholds) and in many ways:
- briefly (against bosses, less briefly) to slow down bullets and dodge difficult attacks
- as a virtual speed boost to dodge large bullet formations
- to stand in front of large enemies and groups, kill them before they go away, clear their otherwise dangerous bullets, and score some gold (a very common pattern)
- less than usual to fill the reserve to the limit of 500 green items, at which point enemies drop gold instead of further green blocks.
