It seems like when multiple missiles hit a target at the same time, not all of them are counted so it only destroys one block. Can you fix this? An easy and cool looking solution would be for weapon groups to fire in succession 100ms apart from left to right or top to bottom, so it's like a wave and they don't all land at exactly the same time.
I can work on changing this, the reason I haven’t fixed it already is that changing the logic would also make enemy missiles that land at the same time do even more damage, making the game harder for the player.
When selecting a weapon target for a weapon group, there’s a barrage mode that you can enable by tapping the right shoulder button, causing the weapons to fire one after another. I’ll play around with the 100ms spacing idea as well!
