@Akarsh, rather than downloading cheatengine, why not right click -> play until you get to the "you win" screen?
and, well, what's the point in getting to that screen anyways? it just tells you that you won... is using a speed hack to win the game really necessary?
i will admit:
the game itself is mediocre at best.
BUT: you're still learning flixel! (as am i)
keep at it, be creative (as if telling you that will help ;P), and keep posting the games you make here.
just keep in mind that not everything in that tutorial is a necessity for games. yeah, he taught you how to add acceleration and whatnot, but is that really needed for platform games? etc. something to keep in mind.
pz.
beat level 24 finally.
upgrade the 6 snaps closest to the exits until you're out of money. send all 25 waves at once. use logic to figure out the rest.
took me 2 tries. :]
