Really love the mood of the music and the environment. The animations on the character feel nice. Explosion moment later on was a nice environmental touch.
Maybe it's a CPU speed thing if deltaTime isn't being factored in, but no matter how fast I start running, I die in 2-3 seconds before reaching any structures. If I throttle my CPU down to 20%, I can get to the first building before the life runs out, but I still die.
If I run left instead, I stop losing life, but the sandstorm never comes back.
You probably want to lock the z-axis (or whichever faces the camera) on the transform of the player otherwise they can run into an angled surface and be mis-aligned from the rest of the level which keeps them from being able to jump on any other platforms after that point.
