R-Type/Stage 1

The stage starts with a few waves of ships flying across the top-half of the screen. After only a few ways, your first powerup will appear - it will land on the ground, and turn around if untouched.

Within the base, you will spot a ring of turrets. Enter when the gap is exposed on your side, wait for the ring to turn around, and exit on the right. Since these turrets launch bullets, you can destroy them all simply by shooting the blue-colored one.

After the ring will be a wave approaching from the top and turning left, along with two powerups, before the tunnel shrinks. You will encounter an enemy that will try launching missiles at you; dodge the missles and fly past it.

Boss
The first boss has two threats - a waving tail, and a semi-homing projectile stream. The tail is avoided by keeping to the left. The stream is dodged by moving up or down, since it stops tracking once it is at the midpoint of the screen.

It is vulnerable to attacks from where it launches the projectile stream. Launching the force at that location should only require you to survive two stream attacks.
