I'd posted this earlier before the messages got wiped but thought it worthy enough to post again. Underground Boxes - Just like any other box but they stay underground and come up from below. They can be collected either by a shot passing through them or being within a blast radius. If the ground is cleared around them then they become normal ground level boxes. Infinite bottom border - just like the sky border. Underground shots don't detonate when they reach the bottom of the screen, but can go below it and come back up. Reverse Fireworks - When the shot hits the ground i acts like a mole shooting the 3 seed shots underground where they detonate into a burst of underground shots that all travel back up and detonate when they reach the surface.
I posted the thing like deluxe that changes all weapons into under ground type. You can change them at options.
i love all of them, but the reverse fireworks should be a whole new weapon with a different name...great ideas!!!!
