The missing piece

This is a short platformer adventure game about an elf named Elfy trying to find its way to the North Pole. I decided to call this game 'The Missing Piece' because I've always wanted to make games. So, this was the peace that was missing in my life; now the missing piece has been filled. 

Join Elfy, the mischievous elf who got lost in the human world. In this adventure game, you play as an elf. Along the way, you have to collect blue-green crystals and orange crystals, which will add up to your crystal score.

You have to find 10 hidden letters to read them. Along the way, you will also find some mailboxes to read what is inside. There are 6 hidden photos to find so that they can show up in your photo album, which you can view by pressing 'z' on your keyboard.

During your journey, you have to fight aggressive enemy bugs. There are two types of enemy bugs: the flying bugs and the one-eyed bugs. If you defeat the flying bug, you will earn an orange juice crystal, while defeating the one-eyed bug will give you a crunchy cookie.
