Good game. Recommended to everyone.
After I did complete level 30 in the scenario mode, I found that this game shows me a well-balanced preference. The gun choice has its own purpose to use compairing with other similar games that , I personally found, not make sense to provide many gun choices but a player doesn't really have to use them. Many different unit types also play their roles effectively which can added varied enjoyment to my game experience. Very nice job!
I do understand that some powerful gun required the delay time before it can be turned. However, even if I keep using the same/fast gun I found that the speed of turret reduce when many enemy units presented which made me annoyed. The music on/off switch sometimes made me annoyed as I required to shoot enemy units from that direction. It would be nice if a game creator can fix these problems! I would give the perfect score without these two problems.
