Theres several problems with this one. The theme is
very unoriginal as there is already a cake map (the 2nd easy map) and the builds are
almost identical.
The parkour is
mostly floating and
repetitive (especially the part inside the cake). The jumps are made up almost entirely by full blocks and cake. Try adding a variety of blocks like piston heads, brewing stands, fences, vines, enchanting tables and water. It was almost too easy even for an easy because there were no challenging or interesting jumps to distinguish the map.
The path of the map was
easy to follow, but that doesn't make up for the rest of the problems.
Finally, when placing "checkpoint" signs type "Checkpoint" on the top row so that staff can easily replace it.
edit: The parkour is also
long for an easy map, (55 jumps) but I did not really notice because it was so easy.
