A perfectly normal shmup spaceship game :) 

Things get even more normal at level 3 and especially level 6

There might be legitimate errors that crash the game. I tried my best to get rid of them, but they might still be there

Controls:

Move:  arrow keys

Shoot: z

Invincibility:x (this is if you have the invincibility power-up)

Three power-ups-

1. Bigger bullet

2. Invincibility (for 2-3 seconds)

3. More bullets

Note: for the invincibility, it comes back in the selection every 3-4 rounds, while the other ones don't come back once you activate them

Accessibility: The game can get a bit chaotic at points, so if you want a more normal experience, press C at the title screen
