Alright, I guess I'll dump my levels in here too.
Take it with you! - 2EC1-0000-0040-6776
A much easier level than what I usually make, but it teaches you a valuable lesson about the spiny shell helmet. You can also try this in levels made by people that clearly don't know about it!
Stacked Sky Decks - DEC5-0000-0015-9419
Sky Deck Act 2 - 7CE5-0000-001C-F776
Two levels focused on being Sonic on an air fleet pretending to be Sky Deck. The former is a cheetah speed autoscroll that you can't take a hit in, because you need to be Sonic to finish! The latter is a more standard level, but its still difficult.
Down and... Still Down? - EC87-0000-0024-2567
A level I started and didn't finish until I got more tools. Its down and then... down, and then back... down again?
Giant Flying Stomping Stilettos - 7941-0000-0026-9759
A level focused on the Goomba's Shoe and how you can modify it with wings and the super mushroom. Watch out, it autoscrolls!
A Prison for Forbidden Power... - E256-0000-0028-2933
Locked away for tapping into the dark arts, Mario uses the last of his sinister magic to make his escape... No matter the cost.
When push comes to shove... - 7AEB-0000-0042-AA25
A bill blaster on a cloud chases you around, but it's ammo is just coins. However, the real danger is that it can push you around in this autoscroll air fleet level!
The Sonic the Hedgehog Xperience - 9048-0000-001E-F3E8
My best level by far, this stage is truly what it is like to play a Sonic game. Absolute perfection.
