Thanks cool to see you enjoyed it :)
I wanted to have a score and a goal however since i still lack quite some knowlege coding wise, so i didn't knew of any method to keep score end display it on a UI, and for enemy variety, i don't know much about making AI yet and, time constraint didn't help so that i could design some more ( which i would have really wanted to ) :p
