Lol those are some indestructible cows!

Beat on normal. I used homing missiles for secondary and tried both primary weapons. By the time my weapon was fully powered I had used both the spread and beam. The spread was good for normal enemies and could help clear the screen easily. For the rest of the game I used the beam for its concentrated damage; I found the missiles could handle off center targets well enough and the beam could very quickly wreck bosses. The bullet hell on the bosses was very challenging but the rest of the game is dull and generic. The most annoying part was how the weapon upgrades would stay on screen and move around in wide circles. So I had to keep on eye on them to try and not replace the weapons, which got me killed a few times. Mediocre game.
