This is cool. I like the way the ninja guy jumps and falls and slides. I have 2 suggestions: the ability to press C/Z to jump (for mobile users like myself), and maybe an attack ability that can be unlocked using X, that lets you kill enemies?

I think the little dude should be able to climb up bamboos!

Good level design. It would be great if you added some checkpoints and instead of jumping with the up arrow, jump with X or Z.

very cool ! i love the animation when the ninja run ! Nice level design

I am working to add flying enemies, a weapon to fight the enemies with, a new jump button (simple fix), and the player able to climb the stalk from the ground.

And checkpoints

Very cool, good job making the sand a part of the level design puzzle. More of that would be awesome, especially with the ice.
