Horsin' around (I lied there's no horse)

Help our main character (let's call him Melvin) make it to the end of this whacky and challenging gauntlet. It's up to you to find out what lies at the end of it! Who knows what surprises are in store! The key to winning is patience, so take your time. That is, if the death counter doesn't bother ya.

Left & Right arrow keys or A & D to move, Up arrow key, W key, or Space to jump. You have unlimited lives and there's two checkpoints. If you're on touchscreen, touch the corresponding buttons to control the player. Press M or touch the sound icon to mute/unmute the sounds.
