Thoughts on playing this:
1) Movement is very unwieldy. It's fluid enough, but I've no real system where up really means up, left really means left, and so on. It's a twisty wheel thing where I've got next to no idea where I' m going to next and I'm leaving it all to chance.
2) What's that thing with the plus sign meant to be? An enemy? Or perhaps an upgrade to collect? Whatever it is, I pass straight through it.
3) The background gets hard on my eyes after a while. It might be worth replacing it with some terrain and walls, or a pleasing patch of ground.
4) That turret is nicely drawn; I hope to see more art along that line because I only have very little to go by.
5) The music is incredibly repetitive to the point of being headache-inducing.
At the current stage I would have classed this as *pre-alpha.* A beta would imply that the game is at least halfway done, there are enemies to shoot and there are bugs that need ironing out. The basic mechanics aren't even complete.
It would have been worth putting this in your Projects and perhaps PMing a few people you can trust to test the game for you, making the game visible to them. As it stands, I, and many others, feel the game is far from ready for public release.
