This is good but it doesn't follow the exercise instructions properly:
"... Keep your gameplay basic for this exercise. Do not use any gameplay objects besides basic platforms/slopes, spikes, and the gamemode portals at the dotted lines. We want to see that you can use each gamemode for its unique functionality, and that you can explain why you chose each gamemode.
When you're done, send a video or a Level ID with your gameplay in exercises. For each gamemode, explain the following:
What properties of the gamemode made you choose it for that section?
What properties of the other gamemodes made you not choose them instead? ..."
You can edit the current gameplay to remove the orbs and pads, and then describe why you didn't choose the other gamemodes (since you've already described why you used the gamemodes you have.
