Growing up on the NES and Atari, I'm a bit of a "simple is always better person." All you need are 1-2 buttons, a control panel, and something to pause the game when you need to take a piss (screw you Atari). That being said I really enjoyed the fact that it was just a strait forward shooter game, for the most part. It reminded me a lot of an NES game called Starship Hector (youtube that one). A bunch of random bullets flying around and you trying to dodge them and take out other units all the while, so you get points from me for nostalgia.
Moving on though, I did find some drawbacks that hurt the game in my opinion. The first is that some of the ships were just roadblocks. If they're not trying to kill me then why are they there? It's obviously me vs. everyone, so why would the enemy bring ships that can't even fire back? It's fine that some are trying to crash into me without firing, but most were just sitting there with no purpose other than something to shoot and gain xp.
The bottom of the screen lets me go so far down that I can barely see my ship. The point is for me to protect my ship, so why make it so I have difficulty seeing where all of my ship is at? Needs to so that 100% of the ship is always in view, as to avoid any damage.
My biggest complaint is the the upgrade shop. This is where you lose the great, simple, retro controls that I enjoyed so much during the first part of the game, and go playstation on me. There are way too many options in the docking bay, and the controls just get sloppy. You don't need elaborate parts, garage, medal collection, or the diagnostic lab. It takes up space and serves no purpose to the main point of the game, not to mention the keys for the options are just bad. Like 'X' to exit 'Z' to confirm, left click to select, move mouse to change selection, alt f4 to self destruct. Stick with one or the other, because right now neither controls are working. The controls are so bad in this section that I gave up 30 seconds in on upgrading but, still managed to progress in the game, so the hassle is not needed. The whole process needs to be simplified! I get so many xp points for killing things, then I can up my armor, weapons, speed, etc. All you need is a simple + option and it's already better.
Again, it's a classic style game, but a lot more time should have been spent on the controls and concept rather than the music and art. Both were ok, but neither of which make the game as a whole any better. I could be flying the Death Star shooting a ray-beam of kittens while The Beatles sing 'Can't Buy Me Love,' but unless things are fixed I'm still only playing this for 10 minutes.
