Super Mario Maker: VegaDI Lvl 1-3
The theme here are Twomps. I looked at their interaction with other elements and constructed the level accordingly. A bunch of times, you have to let them clear the path for you first.
I also looked into flying Twomps, but they were hard to control and they felt like a random threath. So I put them in a closed off area of the level were they don’t form a threat for the player.
