Comparing to the prototype of Level up to this, I would say it looks great. I also have a better idea of why this would not be just another area with Level up game-play. (Not that it would be such a bad thing
I can clearly see the differences in concept from the first project to the second. Just by playing what you have so far.
Not that I presume to tell you what to do, I also will note I have no clue
to what you have in mind for this project, it would be nice however to see a few things.
1. Multiple weapons. Such differences in speed, weight and image.
(maybe having your gun out might keep you from jumping as far, or switching weapons night allow you to jump further. Alternatively having a heavy duty weapon give a big kick back that lets you span greater differences, but not in height.)
2. power-ups, like ammo & health packs . (since it looks like "regen" might be out of the picture.)
That's all my thoughts for now.
