good try
But there are some bugs that need to be worked out.
First of all, it doesn't feel as satisfying to kill the green skulls, which means users will get bored quickly.
also, when you hit 'end game' and 'back', the music overlaps.
easy fix, just put in the 'end game' button
on(press){
stopAllSounds();
}
I hope I helped :)
Btw visit my homepage or pm me if you have any other questions.
There are some things tutorials can't teach, after all.
