My First Gnarly CC

Here we go, my first Creator Contest. This CC will be pretty simple but unique. So here's the rules:
Length: Medium length only, so from 30-59 seconds
Decoration: Anything you want, but try to keep it as unique as possible
Object Count: 15k objects or lower; I just kept it low so people wouldn't take forever and I care about gameplay more; however some cool decoration would be nice
Gameplay: It has to have the spider game mode for at least 10 seconds as its my favourite game mode, and there must be a dual that lasts for at least 10 seconds. Other than that, keep it as fun as possible and make it well synced
Difficulty: Try to keep it 8 Stars to Easy Demon as I am a bad player
Song: Any song you want. I would much prefer a less used song over an overused song
Name of Level: RTef CC1, this will just make it easier for me to view the entries

Due Date: 1st of October will be the latest time I take any entries. I will release the winners on a different thread. I will probably also advertise this CC on a few Discord severs as well.

Anyway have fun creating
