Click on the green flag to start. Use A and D or the left and right arrow keys to move. SPACE to shoot. Shoot space junk for ammo and collect hearts for more health. You lose when either your health or ammo gets to zero. Everything else is pretty self-explanatory. As for the shop: The faster firing speed upgrade can be bought 3 times (each time increases the firing speed). The explosive bullets upgrade can be bought once. The extra health upgrade can be bought unlimited times.
