I love the idea of a bullet hell where you create your own stage, and this fits the theme very easily and understandably. It's interesting how removing a simple mechanic like bullets disappearing can create a whole new experience! I wasn't able to get the shield/bomb to work, but I'm sure with more time I'd figure it out (unless the shield is meant to be able to block things from the start, in which case not sure why it didn't). Great job!
