Nice little shoot em' up! I really enjoyed the use of the assets to create the ships the boot on the player asset did not go unnoticed :D the upgrades to the gun were nice, and I was glad that they didn't expire at all, very nice. Maybe some kind of shield upgrade would be good, as later on I was being bombarded on every side and it was very difficult to dodge (I'm not fantastic at bullet hell games in fairness!)
Good job!
