Thanks for the feedback! I actually wanted the player to have to figure out how to progress, and yes you are right about the billionaire taking money from families and their private island. The enemy can represent the "evil" forces that stop billionaires from easily taking money, or whatever (really it was a means for me to learn how to make such a moving enemy :) )
Was it noticeable that your jump ability increased with each coin you stole from the families, and that you have to steal them all to make the platform jump possible? I fiddled with the increase increment quite a bit, but maybe I landed on something too small to really notice...
