Great game! I bought the passive upgrades first and since I had regeneration I could kill the last boss with a not fully upgraded gun. I wish there would be more levels. And I want my dog back! Where's my doggie?
I like music and design. But the game is too much based on luck. I played until level 18. I tried level 18 twenty times and finally gave up. The only way to pass would be to refresh the level until you can start with a special move.
