Not Bad

AN alright game in my book has that old asteriods feel to it which is a nice change of pass, keep it up.

hmm..

not a bad game at all, you could make slower enemies and more enemies at least e.x blue and green if guru is the hardest level it's somekind of easy,just spin around while holding space and you easily get 1000 kills. but it has nice graphics and a lots of potential this is the first version though..but don't give up just make it

a)harder
b)a little more entertaining could be done by upgrades bosses and some levels.
c)work on enemies, kiling alien heads made me chuckle a sec...keep up, i know this will grow big.

is it enough???

maybe you should make level's in the game ya know.... and upgradable weapons.... and tougher enemies

Too easy

All you have to do is spin on the spot and occasionally move to get health pickups. Also if you're going to include a help feature try and at least help the person who's reading it. It was the same all the way through and wasn't very interesting.

Needs sound

Put some sound in it and it sould be alright
