Hello petlahvicka,
I regret to inform you that your map is REJECTED.
The THEME of your map is original as there are no furnace maps on the server, so good job on that!
The BUILD of your map is a problem. The main build of your map is entirely 3D pixel art, which is no longer accepted on ManaCube.
The PARKOUR of your build fits the difficulty for an easy map so good job on that! The length of the parkour is too long for an easy map through. Your parkour is lacking variance, only things that are incorporated are regular jumps, fences, and ladders. To add more variance, try adding more jumps with unique blocks like pots, water, heads, vines, etc.
