You guys are rad. Thanks for downloading and checking it out even if it ended two minutes later with you totally frustrated and not wanting to play. Double thanks for taking the time to post your feedback here.
There's a very slim chance we are going to let Champ walk. We've designed every level around him only being able to use the grappling hook, so it's almost out of the question.
But that doesn't mean we're throwing your feedback to the wayside. You've all brought up great points and problems the game has. We think there are some other ways, besides adding the ability to walk, to address the issues brought up.
Like I mentioned in my previous post, we want to add the ability to add momentum to your swing by pressing the arrow keys. I think this will address the problem of getting stuck underneath places, or not being able to get the exact angle you need to make a jump or climb a ledge.
Secondly, we are planning on adding a camera pan so you can check out the areas around you before going for a huge jump blindly.
I'm hoping these fixes will make it a lot more accessible without compromising the original vision of the game.
@rlc_nm - Cool I'd be happy to make the tileset public. I don't really plan on using it again. I'll post it on my tumblr or something soon.
@brettchalupa - Yeah we were going for a more strategic/calculated approach, so we didn't want to allow double grappling. Oh and thanks for the detailed pros/cons list.

@ortoslon - I get what you're saying about the vertical speed. We'll look into that for sure.
