Level do

3403 Year. Level-1.

The main character, Bart, hit the most mysterious place, where
deeper of all. This place is called "Level-1", because
this place was the lowest, and the higher the level
getting bigger. And after 12 years
Bart after "got out", told
interview that he found friends who helped him
get out of this place, that there he met a lot of monsters,
and he saw many unresolved objects!

And now this date has explained everything, 3415 year. But everything? Or
is there a mysterious place under level-1? #adventure
