I liked the game itself alot!
But... with most every game there were a few errors...
1.) Once you get the AirStrike, after a few levels, the bar just stops recharging, but you can still use it, you just have to guess when it is up.
2.) I got Baricade 1 all the way up and then after a few levels it went all the way back down...
3.) Not really and error, but it was too easy when you get higher level, but it is really fun.
I liked the game alot, and don't take my errors to any offense.
Thanks. ^^
