ok I'll be posting the rest of the ideas here 1 cool gimmick would be meteor showers don't really know how it would workd but i think it would be cool 2 a cool theme would be space where you would have to survive a range of cosmic disasters 3 another cool thing i think could be a shield for the boss that you have to break and the shield comes up every now and then 4 maybe a grab attack? i thinking of designs for the boss and i thought maybe floating hands a grab attack would be cool :) 5 maybe a minion attack where you would have to dodge smaller homing missile attacks 6 maybe the background changes he could have a entirely new phase of fighting 7 maybe if you add a collectable shield he could have a scream attack that would break it
