I'm glad you liked the concept. Due the time, creating the coins was my way to have the Hero "fighting back", because some of the ideas I came up with would take more time or the implementation didn't feel as intuitive enough to figure out in time. I also thought on some ideas to make the Hero's movement less predictable in some ways, like make them go in random directions sometimes, but I felt it would overcomplicate the game (at least, for this version), but are things that I'll probably think about it if I eventually work on expanding the game. Thanks for the feedback :)
