Excellent little game!

I didn't make it past level 4 yet though, but i'll give it another try later on.

It looks a bit like robotron, except you dont have to rescue people, but instead shoot lots and lots. Which actually is not a bad thing at all.

Three things I noticed,..
A) the tripple laser not only has 3 bullets but can fire quicker too. I'm not sure if that is intentionally done or not, though.

B) when I die I have to push a button to continue. However, because it also gets trickered by an arrow key, I rarely see the end screen.

C) The key configuration is a bit odd, but not so much that it gets in the way of playing. That is with the exception of the spacebar. I have to move my hand too far to make the bomb really benecifial. I'd recommend using one of the mouse buttons instead, as they appear not to be used right now.

Add a few more baddies, a few more effects and you have a great little game in your hands!
