Pretty good, kind of tricky. I like it!

It's a nice start for your first game on NewGrounds! If you're going for rage, having to restart from the very beginning if you die was a great way to do it, although ofc that might hurt your score from players. I like the fact that even though it's a simple game it pays attention to important playability details like zooming the camera appropriately at different points in the level. I'm not sure if the auto-repeat jumping as long as you're holding down the jump button was a design decision or sort of accidental -- it did make the elevator kind of funny, but it's an unusual way of doing things in a platformer that felt a little off in other parts. I look forward to seeing what you come up with in the future.

Well, this is certainly better than that other game! I don't mind the graphics being primitive! At least there's sound. Could use some music though.
