So one thing I noticed, every level I played told me I was on Level 1.
Would be nice if the music was quieter.
Shouldn't be able to mouse-over any buttons while a level is loading.
Would be neat to warp in at a random place.
Next level button should move to the next level instead of the level selection screen.
There's not much of a direction during levels, or real danger. I simply turned towards the boss and shot until I got through his shields.
Opening radio sound byte hurts at normal volume.
Maybe consider limiting rate of fire? It's really easy to spam the lasers, and no real reason not to. I could just rig up a macro, hahah.
Shooting star things on the level selection is kind of confusing. They look neat but are reeeally distracting.
Levels do not seem to save unless you hit "next level"? I went to the help screen and it didn't save completion of the first level.
Yeah, those're my quick thoughts and such.
