This is a side scrolling platformer featuring colorful graphics, challenging levels, advanced AI, and a lot of other stuff. The objective is quite simple: destroy all the crystal poles and find the exit! Yet it's not always as simple as it might first seem. A lot of challenges and different enemies will try to stop you before you reach the exit of the level. However, you can fight these with your plasma machine gun. Every moving enemy can be eliminated with this weapon, it's just a question of hitting them enough. Your ammo is infinite, but you can pick up limited ammo which increases your firing rate threefold and thereby helps you out a lot, so look out for them.
You are introduced to the gameplay in a tutorial, so don't worry. :)
