I might be dumb, but I have no clue how to beat the "Rampage" level.

if you get stuck you can try looking at the playthrough I posted (there are timestamps), have you playe through the tutorial? you just have to kill all the enemies then grab the crystal. Make sure to play the tutorial. - To kill enemies left click to lasso them, then swing your mouse to the side to fling them into a wall. they will die on contact.
