Hi.

I Hope the msc goes well.

As regards the game, I completedted it on my first go too . Firstly the idea is rather unique. We have seen lots of space invaders games in audio, see this list for details indeed it's such a common theme for an audio game that it's got it's own catagory on the site, however with the system of ships moving across and the control scheme you have you came up with a rather different take on this which was good.

The problem however was that because all your ships moved left to right, and because your guns could shoot as soon as you heard an alien ship on one side or the other, I found the game turning into something of a boppit clone, ie, just hearing a sound on one side or the other and hitting instantly, indeed I don't think I ever pressed space bar, f or j throughout the entire game I just used the d and k keys everytime I heard something at the sides.

You might therefore have a think about altering the distances, speed and range of your guns, indeed as a general point this is one of the major problems in audio game design, trying to produce a game that requires as much of the players' judgement as just being a quick reaction fest. After all, in graphical space invaders you need to line yourself up with each falling ship, dodge shots etc, it's not just a question of hitting a button.

so this is something you might think about in expanding the game, since it is a unique idea to have a left to right moving enemy.
speaking of the enemies, the sounds in this game were great, and I particularly liked the way that different sounding enemy ships appeared throughout the game which kept the audio particularly interesting to listen to and is something I do hope you keep even if you plan on expanding the game with different ship types etc. the only thing the sound was missing I thought was a good explosion affect since blowing the ships up wasn't quite as satisfying as it could've been, likewise, some victory or death sounds might have been good, as might maybe some different background if you plan on expanding the game, though the electronica beats you had were certainly retro enough .

that being said I really enjoyed the voice acting and story, I got the distinct idea that the ship's captain wasn't someone to argue with .
I also appreciated the fact that the story and instructions were all part of the game, rather than just generally presenting you with a "blow up as many ships as you can" sort of motivation as most arcade style games do.

I do hope the game gets expanded, since there is a lot of potential hear provided the gameplay can be made a little less of the hear it, hit it style, as well as obviously making the game longer and more challenging.
