To be able to compete with better players you should rebuild your maze at least 3 times.
Pellets right at the entrence work best in the first 20 levs or so then you should switch to squirts.
In late game one big group of ICBMs with boosts in the middle seems to work better then bashes. For the lev 42 and 49 fliers you should build storms then sell them.
At the last lev you could use snaps to kill them faster.
