It's a good game, but I think the ships' shooting is very weak and unbalanced, the snow that is slow is really slow, the ship that has the weak shot is too weak and so on, would it be possible to improve this?
If you press the A button, when you have the Burst bar filled, you will exchange the bar for a PowerUp (which can be either Speed or Power). Otherwise, if you break the burst bar using the C button, you will fire a burst of energy
