A small update to include a few things that every good shmup needs. A power up, a bomb pick-up and some bonus items. There's vertically and horizontally oriented versions of the bomb and power-up and all the items have an appear / disappear animation sequence and a flash effect.

I've also added a bullet "evaporation" animation so the bullets can transform in to bonus items or be cancelled out by a bomb, shield or [insert your favourite shmup game play mechanic here]!

I've also been experimenting with hand drawn rotation frames for the small ships so these might make it in to a future update. On top of that I'm planning a separate asset pack to build modular bosses in the same style as this pack.
