Hopefully the game doesn't look too confusing. Here's how the system work.
- Press Z to shoot. Hold shift to activate soul collector. Hold X while holding shift to rotate the soul collector.
- A killed enemy will leave its soul, which can be collected by using the soul collector.
- Once one or more souls are captured, you can activated 'Soul Barrier' by releasing shift when the
second bar at the top is max (You'll notice this when the soul collector circle turns purple)
- When one or more souls are captured, you soul collector circle will slowdown any bullets that are inside the circle. However, this will constantly decreasing the soul collector endurance (red guage to the left of your character) When the endurance guage reaches zero, one of the captured soul will be destroyed.
- Soul Barrier will transform any intersect bullets into bonus score items with each one has a value 1,000 x current multiplier.
- Releasing shift before the guage is max will resulting in 'lifting' which is exactly what it does. Think of lifting a ball in soccer game. You'll release all the captured souls and push them toward the right side of the screen. This can be used to capture the souls again to reset the endurance,
- Releasing shift when the guage is max AND just before you ran out of endurance is called 'just timing'. With just timing, the created soul barrier's current multiplier will be double, triple, quadruple or even more, depending on how close your endurance is almost run out.
Maybe I should add a video that demonstrate the just timing soul barrier.

P.S. No, I'm not gonna use this music in the actual game lol. Doesn't really fit to the game at all, IMO.
