I've powered up the guns recoil and limited it's shots.  This will now replace the old jump.  Dash has been moved up to RB so now jumping/dashing/grappling can all happen without having to take your thumbs off the sticks.  I think it works well.  I made a super easy first level to get the hang of jumping.  I will add more that go over the different mechanics as learning levels.  There is an attempt at a TNT block in-game now.  It's functions/visuals are still being worked out.  All sounds in the game are place holders.  You probably shouldn't play with the sound on, it's pretty brutal.
