Love the game! Maybe you can add the option that you can sell an item if you bought too much accidently. and an option where you can buy not by cliking but put in the amount in the box, sometimes I need 300+ pieces.
How the hell, you get some descent HP when you die, I always have 25 or 10, it's almost impossible to get 100 back. Need's a button in the shop to buy healthpacks.
