The ledge grabbing mechanic is something I haven't really seen in a platformer; it makes this game stand out a little more. I think the implementation of the theme was fairly weak because the game would work just as well with the spikes being a goal and the coins being some sort of enemy. Still a fun game though!

I love the concepts and the execution! I had a bit of difficulty using the up arrow key as Safari would try to keep scrolling the page instead of grabbing a ledge, but it added to the challenge.

Nice game, I liked the warping and ledge grab.

For some reason my browser (firefox) kept scrolling when I pressed space, which made playing hard until I realized you can jump with shift.

Very neat! The tutorial is nicely designed and taught me everything I needed to know in an efficient way.
