Pretty cool retro entry :D
I like the way you made elements powerups for traversal, it was so cool to create those ascending air currents by using the air elements on the fire hazards.
While i liked it as well, i felt the earth grapling hook thing was a bit harder to use especially when you have to leap from one grapple point to another quickly, which brings me to my other only issue i had, the checkpoint hearts are really far appart so this made dying quite punishing :o
Other than these, i still had fun regardless, i like the light and particle effects you made, it pairs really well with the sprite style you went for.
Plus gotta love that early NES style cover art so cool !
Overall good job :)
