First of all, don't use fullscreen since it's broken.
Edit both keyboard and gamepad controls to default even if you don't use a gamepad. ( You can change this later.)

Default controls on keyboard:
T- Pause
Z- Attack (Confirm)
X- Attack 2 (Cancel)
C- Hyper Attack
V- Dash
S- Shield
Hold A to- Change Z X to special attacks
Hold A and C to- Do special Hyper attacks

Basic tips:
-As you dash you gain heat and receive more damage proportionally to it.
-Some projectiles such as missiles can be shot down by other shots.
-Many weapons can be charged or tapped to change power levels or amount of bullets.
-I recommend changing the special toggle from A key to something that can be more easily pressed such as shift.
