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.
