Well...
With some more polish, some fixes and updates it could be a pretty cool game.
I actually did'nt care for the style but that's an opinion so no worries.
If you jump and come in contact with a gain/Rope you should automatically catch, and some other annoyance that kinda get in the way...
With those out this game could be awesome. You did a good job. Oh and make the chains look like chains if you can =D
