Space to shoot. Shoot the target for money. You can exchange money for upgrades, like auto and gun upgrade. Auto: automatically gives you points every 3 seconds. Upgrade: makes your gun shoot 2 bullets and at a faster rate. (slowly double-tap 2 shoot 2 bullets)
UNFINISHED: I will add more upgrades Thanks to @graykeis for the idea!! All code is mine. I will later add more upgrades. Please comment on ideas to improve!
