Pros:

Vanilla Ghost House from Mario!
Ghosts!
Puzzles
The rescue vehicle's kinda cute =D

Cons:

Very difficult to play with bots
Those dark areas

Conclusion:

You need to explore the whole map though, like the dark area thing on the hallway with circling chain of spiked balls (There's a ladder there that seemed to lead to nowhere but if you continue to go down you'll be in a bright tunnel.).

This is a great map.
Perfect to be played with Mario mods.
This thing needs to be more scary, like adding jump scares.

You better try it.
Especially for Mario Fans.

Made some more.
=D
