Hey JJ,
I won't reject or accept this course at the moment and I will tell you why and what I want to see.
I really like the lighthouse. You built it well and the jumps are decent as well.
2 things are bothering me at the moment: 1st keep the jumps in the insane difficulty and don't try get it too hard (I like the door jump btw. I mean the 5 blocker momentum) Some jumps with momentum are really hard to do on creative, since you cannot use /cp and you cannot momentum, because of fly in gm1 . Try to avoid that if possible. The 2nd thing is, that this sea lantern cube, ruins the nice looking lighthouse. Instead of a cube, maybe add water, boats, ships etc. Stuff which fits better into a lighthouse design.
There is already a lighthouse course and we only accept yours, if it is way better, than the old one and also nice looking with a theme (Not only a lighthouse with ladder jumps). If you maybe improve it a little bit, we will accept it, but you can message me on here always, if you got more questions etc. Sorry for the long text, but I am trying to help you and try helping you improving. Thanks for submitting and I hope to see editing on your course
