Love it! but really put auto fire :D my finger is tired

I really dislike that you have to keep pressing the fire key.

Also, there's a white bar, about two pixels wide, on the very left of the Flash.

Please move the hud to the bottom. Upgrades are great, but OP, after lvl. 3 A and P all I had to do is keep shooting while moving from left to right and that pretty much cleared the whole screen, did not get too far, will play later, maybe we get tougher enemies later stages...

Well presented, but completely irritating.

HP of enemies increases suddenly after the first dozen so you need a power-up which you may or may not get, especially irritating when it's near the edge of the screen where you can't pick it up. After leveling-up a weapon, picking up a power-up at the wrong time leaves you with a totally useless weapon.

Enemy shots would be better a bit larger to make 'em more visible

The aim is to make it fun for the player, not to kill 'em off ASAP. Take a look at Zenon Mega Blast, StarMada or Frantic for how it should be done.

You Fail

It's a nice game, clear concept, but I would advice you to make the stages a little shorter or the shooting easier then it is atm. ;)
