It... is done. Here's the rest of the screens.
Just a small notification.
This is a secondary exit to the first section's room.
There's the home stretch!
ffs red tile down there
This level is completable under 500 seconds. I leave Mario alive if you ran out of time, so you can finish it instead of having to do it all over again.
Here's the times:
The first room should be about 200 seconds.
The 1st vertical room transition + Subroom 1 should be about 100.
The 2nd vertical room transition + Subroom 2 should be below 50.
The 3rd vertical room transition + Subroom 3 should be below 50.
And the rest of the vertical level and the last section should be greater or equal to 100.
Which all adds up to 500. As far as I recall, It's okay if Mario doesn't die at 0 seconds.
With that said, Enjoy.
