I don't know what i have done, but i'm stuck in the middle of the obstacle :(

Hello, I just released my first game on itch.io !
Beyond the ice palace is a 2D scrolling platformer built entirely in JavaScript. Embark on a heroic mission across three monster-filled levels, fighting enemies, collecting weapons, and summoning mystical Spirits of the Forest to aid in tough battles.
The game was available in many 8bits and 16 bits computers like Amstrad CPC and Amiga.
Playable directly in your browser: Link
Commented source code for sale to create your own platformer game, include tools like Level editor etc...
