Super Mario Maker: VegaDI Lvl 1-2
My theme for this level was fire. You have fireballs coming out of pipes, lava, a Cheep Cheep on fire, Charizard as the ? mushroom, rotating fire columns and Bowser Junior at the end.
The biggest challenges of the levels are the Cheep Cheep on fire, as it will follow you around, and the tricky jump at the center of the level. Although I have not done it in my playthrough, you can actually jump underneath the fire canon and force it to fall of the spring.
