It looks like there is a lot of stuff implemented already, but unfortunately I wasn't able to get far enough to see it.
My first playthrough I managed to beat the tutorial level, then I got a bit confused by shop options, and accidently bought a health pack instead of repairing the ship. Next level I got killed. I tried restarting serveral times after that, but the tutorial kept breaking for me.
Some thoughts:
1. It is very easy to break the tutorial. I noticed that just tabing out is one way. But on my last attempt I tried to use tab only when nothing was happening, but after breaking up the first asteroid I still ended up in a limbo, with nothing happening.
2. Point management seems very unforgiving. Maybe rapair could be free? At least initally?
3. Inability to restart without the tutorial is a bummer. It seems like the game is simple enough, the tutorial really should be optional. I usually lack the attention span for that.
4. Animated border is a bit confusing, makes me think I'm moving when I'm stationary. I know animations are nice, but maybe something pulsating instead of constant movement would be less confusing.
The game is very pretty and seems to be on the right track, at this point the tutorial seems to be more trouble than it's worth tho, at least for me.

I thought I'd eliminated all possible issues with the tutorial, save for the asteroid possibly not shattering correctly. I did not test it extensively in the web version though, bummer. I'm uploading a downloadable version with a skippable tutorial now (can't believe I forgot about it), web version when it finishes building.
