I play through the first 3 missions so far which is like 30-30 waves or so. I think the game is good.

I think graphical quality is good. I like the music and the sound effects.
It's a tower defense game. If you have a played a lot of these types of games before I wouldn't say that it really innovates. But so far I think a pretty good implementation of this type. It has few useful features. For example if built something in the wrong place you can get a full refund if you sell it straight away and you also speed up time during the waves, so that the game isn't so slow. You seem to have good variety of turrets to build. Some require you to have a tech structure first. I noticed that there seems to be only 15 levels, I'm not about that though.
The game is easy to get the hang of the basics such as turret placement. You need to get to know the characteristics of the different types of turrets. Obviously some ordinances are more effective against certain types and amounts of enemies. However rotation speed of the turrets also comes play, some are very fast while are so slow enemies can get past them.
I like this game. I like trying to find the best turret placement, combination of turrets etc. It was fun. But if the game only has 15 levels it may be relatively short. However later levels should be increasingly difficult and have more waves.
for more let’s play videos =)
