Hey Hayley and TimTamTum!
I am here to give you my review of the map! Please remember that I am only a casual player and that my opinion doesn't affect whether or not the map gets accepted.
Firstly I think this map has
POTENTIAL. Hear me out!
The theme of your map is GREAT since I don't think there are any other maps based on Finding Nemo. I could always be wrong though, great job on the theme!
The build of your map is
AMAZING. It is very accurate to what you were going for, has block variety and all the little details. Truly astounding, amazing job to the builders!
The parkour of your map is NOT GREAT. It is varied, but it's more like chained. What this means is that you have sequences of certain jumps and then other jumps. For example 5 soulsand jumps in a row and then 5 fence jumps in a row. Try not to sequence jumps and instead try to have continuous jump variety. I also think that the parkour is WAY TOO HARD for an
Expert map and I think this map has more potential to be an
Insane map. The difficulty is much more suited for an Insane rather than an Expert and I recommend that you don't go nerfing it and just try to get it accepted as an Insane map. It's up to you though! The parkour also has other flaws, which I'll tell you right here.
Luck ladders and vines
These parts are entirely dependent on luck rather than player skill and should for that reason be removed and switched up to something else. Please change these parts, they will be annoying to fail if the map gets accepted since the player can't do anything about it.
A huge exploit
You can simply jump down from the start platform and go around these barriers to skip at least half of the map. Simply add more barriers to patch this.
EDIT: After testing the map further I found another skip! (Green arrow indicates where you should go, red arrows indicate the skip)
The map also has teleport blocks which I think are currently broken so it might need some interesting techniques to make the teleport parts work.
If you fix these issues in the parkour I think this map is definitely being accepted as an
Insane map.
Good luck! :)
