A Small Tip for Players

We know not everyone is comfortable with fast-paced shooter games,

so we’ve included a small hidden trick for those who need it:

👉 After entering a stage, press G

👉 Your ammo will be instantly refilled

⚠️ Please note:

This trick significantly lowers the difficulty

and may reduce the intended combat tension and challenge.

If you want the full bullet-hell experience,

we recommend using it sparingly — or only when you’re truly stuck.
