Thanks everyone!

The power ups (score multipliers) come from enemies that you kill. Sometimes, if you kill enemies off screen as soon as they spawn, the multipliers fall down without an enemy nearby. Your ship's gravity sucks in the multipliers as you move close to them, but if you move too fast they get catapulted away.

I'm not sure about the boss going off-screen - he does follow you but he moves really slowly. I think that it might have been one of the heavy enemies that tries to avoid being hit.

The first boss:

I like the 1984 feel and the auto fire is interesting, but I'm not too sure about the powerup acquistion. It would be nice if I knew when it was coming...
Also the graphics are a little too colorful and too chaotic for my eyes.
The JUICE is there. The feedback for collecting star drops is nice. 
I love the space jump transition
And A+ for harnessing the power of the internet and getting that leaderboard up and running.
Also that first boss guy keeps leaning almost off-screen which is kind of frustrating. WHY YOU HIDE FROM ME BOSS GUY?
Anyway thanks for sharing :)

The concept o this game is of course nothing new, but I really like what you did with it. It looks really good and the game feel is amazing.

Solid Game :D!  The aesthetics are amazing.  Each time I go up against a wave of enemies I feel like the coolest guy in the world coming out on the other side!

It's fairly good, but the mouse-control feels too exact, like i'm not doing enough. turns the experience into more of a mind-numbing stare at the screen than an engaging experience.

Thanks for the kind words, it really means a lot!

Be sure to check out the online leader-board and boss fights too if you have time later.

this gameee brooo! aesthetics, sound, gameplay  all rly good :)))

I really like these types of games! The projectiles were hard to see, but other than that it's a great game.

Great game, the aesthetics are really good, just give the enemy projectiles a uniform color.
