Got a score of 250k
Level 34
(I will post a pic when I get home)
Here are some tips
1. Learn how to small jump. You should be able to jump from the ground level directly on top of the POW. You do a small jump by timing your jump. Push the joystick in 1 direction and while it is returning to center and your character is slowing down press jump - you will get a jump that is just as high but doesn't go as far.
2. POW - when standing on the middle POW, you are safe from everything but the orange fireball. You can jump over the blue fireballs, none of the creatures can get to you and the ice cannot hit you.
3. Pipes - you are also safe(ish) on the bottom level on the edge of the screen with the pipes. The creatures can't get you but you need to watch the blue fireballs and red fireball.
4. On a dual crab start first level, start off on the POW to knock them both out.
5. Do not kill the orange fireball unless it is the end of the level. The fast moving fireball is difficult to time.
6. Do not linger on a board too long. After a while the orange fireball goes away and is replaced with the fast orange fireball.
7. In the later waves, the longer you are on a level the more likely a blue fireball will appear. I will hang out on a level below the level I need to be on until the last second to try and get the blue fireball to appear on the lower level.
For fun and a few extra points, try to get all but 1 of the turtles knocked over on wave 2 on the middle platform. You can always retreat to the POW for a quick breather.
