Hi everybody,

I finally added a cruddy, buggy version of a card shop and a level restart to the game. Now, every level has five zombies to beat and after beating them you get the choice of one three cards to add to your deck.

Known bugs:

- Lightning Strike crashes the game when no enemy is present

- Shop sometimes offers more than three choices ( randomizer logic is probably flawed)

- Powerball gets semi stuck on border wall (I suspect some kind of tunneling effect)

- Refresh Orb Card doesn't exhaust and additional refresh orbs don't stay on the field as intended

- Many more I can't think of on top of my head

Any Feedback is very welcome!
