Like all previous games you've made this one rocks as well! Nice retro graphics, gameplay and sound, it all contributes to addictive game.
However, I found some bugs:
- some enemy particles stay still if you get them off the screen and then return back (when you come back they start moving again
-And some highscore table bug (attaching a picture)
PS: Yep, I made it to the top of highscore ^^ (didn't kill last boss though)
