So, first thing, I love this concept. Makes sense for the theme, and it's a cool new way to platform! But, sometimes the penny seems to just do its own thing? Like fly around or go in a different direction than thrown. Also, the penny doesn't push the character quite as much as maybe it should, leaving a pretty slow and frustrating control scheme. That said, I really do love the idea, and a few tweaks could really get this game in fighting form.
