This is really fun! I've always enjoyed making numbers add up. At first I didn't understand what the green bar was. This is a great interpretation of Blackjack as a casual game. Thanks for sharing!
The good:
1. Drifting tanks. Neo: "woa."
2. The weapons! Tons of em! They're all really fun
3. Survival mode is intense.
4. NO SHOPPING! It's nice to have a good old fashioned arena shooter.
The bad:
1. Can't turn left and shoot at the same time on this laptop. Maybe z or x could be shoot instead of space?
2. Arcade mode is super slow paced.
