About the level. It's not too bad but not that good either. Idea is good, but the clash is real! Especially these SMB1 goombas look uhm... bad. Also these bricks. SMB3 bricks and enemies from Zelda aren't really the best choice.
I was not expecting someone to make a video of my level so thank you. Also, I just found a level called "Panic" on "The Invasion 2". I might change my level to be somewhat like that because I found out that it's somewhat short and easy.
