Desert Defense (MaratG2, Rubyes)

Try to defend as long as you can, but you won't survive. My personal best is 22:11, can you beat it?

Upgrades info:
* You can have only 3 weapons and 3 passive effects in one run
* All weapons after lvl5 can be upgraded to super lvl
* To unlock the super lvl you also need to have certain passive effect
