I think this is going to be a very cool game.  I hope you continue it.  The only thing I had issue with is that it was really hard lining up the shots.

Very fun game. 

The camera problems have already been mentioned below. I would add that the resolution in the browser window does not change, my entire game window does not fit on the screen. It is quite difficult to aim, I would like some kind of sight. Also, the enemy hitboxes are not very clear. Overall, I liked the lack of bugs and the atmosphere.

Well done, the mechanics were pretty fun! Would be a cool addition to have some sort of feedback or hit flash so you know you're doing damage to enemies.

I like that it reminds me of Space Invaders and Jeff Minter's games (e.g. Tempest) at the same time. I wish the grid was more visible for clarity, but I can appreaciate trying to have minimal GUI.

I like the aesthetics and it's strong on theme. I wish there was a boost button or something to go faster.

A bit hard to control due to the camera movement on the web version but it is an interesting rail shooter concept.
