I think the concept works - needs some polish.
Quick rundown:
The Good - The starting speed was a good 'ease your way' into it introduction, the controls felt tight and responsive, I found myself making minute microcorrections and felt the ship was responsive, if there was and drift, I would have been put off a lot. I liked that pressing 2 keys at once gave diagonals as well.
The 'meh' - It was difficult at times to tell how much space I had to maneuver, or when I was getting too close to something, perhaps the wings are a bit too wide. The art (while I'm sure was placeholder) was a bit too 'generic sci-fi'
The Not So Good - I really did not like the music, was too loud (I'm certain its placeholder as well) and the menu to turn it off did nothing, I kinda wanted to hear more spaceship sounds. If there was an option to shoot, it wasn't readily apparent.
Its got potential - what I'd totally go bonkers for is to see this in VR, kinda like Xortex and Valve's 'The Lab'
