Oddly Entertaining.
The movement and level design is much more complex than what I was expecting once I saw the graphics (which are admittedly terrible).
There are a few problems with the control scheme once you get the grappling hook/rope it becomes difficult to slide instead of shooting the hook, since it requires basically exact timing. The mine cart part would have made more sense with the control scheme if it had used the up arrow and C rather than XZ. It also seems like the collision detection could use some work, mostly in regard to the saws.
Improve the art/sound effects and fine tune the control scheme and I could see this having a fairly good sequel.
