It's addictive!
It's been a while since i've played a game on newgrounds more than once. I'm on level 22 so far.
@JoeGame9, on lv 16, make your way to the green switch, ignore the red switch, and when you hit the green one, go to the flag, while avoiding those silver things.
@supremesonicbrazil, on lv 15, hit the green switch, then go back to the armor power up thingy, but don't pick it up. go to the area with the red blocks, and hit the red switch. go to the left where there's unmovable blocks and go down the hole while holding left. pick up the chili pepper power up, then jump down the hole where there's fire around it. make sure you hit that coin, and hold right until you get to the area where there's blocks and coins heading up. hit the last coin, then hold left. then pick up the armor power up, and jump back down. Break the blocks and use the trampolines to make it to the flag.
Hope that helped.
