Retro FTW
I'm playing this game for a while now and really like it.
The graphics are simple, but in a good retro way. I really like the neon-like art style. This and the catchy background tune reminds me of the good old times.
The game itself, game play wise, is also appealing. It's a pretty cool mix of different games. Shooting aliens with gargantuan cannons is always fun.
It's not the easiest game I played so far, but the controls are easy and the action, especially on the later levels, with missiles, lots of aliens and motherships is quite intense and a lot of fun.
I can only recommend the game. It's fun, it seems well done and the amount of content, lots of levels and medals to gain, is enough to get me entertained for a couple of lunch breaks.
