Nice game, I made it to #38 in the highscores
The music is pretty cool, I especially like SurfOnaSineWave.
Some suggestions; Before a game, when the scroll text and highscores are displayed (I call it "attract mode") maybe you could also insert a screen that displays instructions and all block powerups, like (L-block) = large paddle, (red block) = laserbeams, (green block) = glue ball etc.
When you catch the nuke-powerup, maybe all blocks can shake, or maybe the entire screen.
At first I thought the portal blocks were movable blocks, because of the icons. I think another icon, like a round wormhole thingy, would be better.
The level skip at the end is very clever (to prevent the gameplay-slow-down at end of level), but I think you shouldn't have to press a button to make the level-skip meter rise. Maybe it can rise automatically as long as you stay inside the small area.
edit:
#3 now! :
In my first attempt, I used level-skip all the time but I didn't realise that it drains all your points.
