The obly thing I suggest is to max out you build a bot or the spaceship booster thing. Once you've done that, make sure the 2 colour bombs are next to each other. You can exit and re enter levels without losing your boosters or lives. Make sure you get the set up with 2 colour bombs are next each other.
You can go back and complete previous levels to max out the build a bot or the spaceship booster thingy. I suggest going back to the start of the game and completing the eaoser levels.
This is what I do wihh most levels and it's how I've got so far in the game.
