Well, look at that we got a level to play let's go.
So first of we start rather simple, the only thing i kinda disliked was the smb1 blocks used as ground but that might just bug me. Theres a Hammer Bro which dies after you hit the switch infront of you. While the HB can't really do damage and is rather useless we move on. I am not to fond of these bridges as imo it would be enough to have the blocks there as you barely see the bgo anymore after you hit them. Another thing i kinda disliked were the smb1 clouds used in this. They didn't really fit into it. The Bridges aren't really different but one thing that get's different is when you have to jump from block to block to get further. SOmetimes you meet some enemies also but only goombas, koopas/parakoopas and sometimes another Hammer Bro. After a while of walking to the right hitting some switches i realized that i disabled some of them so i had to go back and hit the same switch again to reactivate it. Could be my own fault as i didn't know i would deactivate them again as i though it would be the same again like before.
After that we get some.. plattforms? Well, one thing i didn't get was this:
First off imo idk if it's that good to have the lines behind those bgos. Second the switch block is useless and if you hit it you die.
After that we get another travel
and after that another one which almost killed me also:
The bad thing about it that you can't see when the ride ends so you don't know when to jump also which could kill players if they don't react fast. Yes i do know theres another switch that actually helps but it doesn't change much.
SO practically the level wasn't bad but wasn't that good either for me. I wasn't fond of the use of the bgos, the smb1 clouds.
My minium i would give would be 3.8 i might be a bit harsh but theres still improvement in this level. You could still do a level like this but maybe a little different.
