This is the second game I've submitted online, although the first on Newgrounds. It's pretty old school-ish arcade style with all original content. There's no learning curve, simply use left and right to move the ship and space to fire. Pick up the upgrade cannisters to increase the fire power of your ship. Learning the enemy's AI is important to get past level 6, unless you're really fast.
It doesn't have a real story
You just go from lvl to lvl not doing much and you don't get to keep your upgrades and there is no real interaction with your ship like being able to customize it. If you add a few things it would be a much better like different music or some sort of way that it showed you moved to the next level not just the enemy ship getting faster and stop when you shot
