Lost in the labyrinth of fire, map generator test.

[The Shadow]

In order of how you brought it up:
Yes, the floors cleared is supposed to dip into negatives if you abuse the escape or the entrance too much.

The maps would regenerate so fast you might not be able to see it.
(Working on this now)

Luigi was able to place a bomb in between grid cells, allowing him to explode an are much bigger than is supposed to be allowed. (a 3x3 blast radius)

Well that's no good.
I was able to recreate this glitch by pressing the regenerate button while the game was paused. This will be fixed in the next version. Thanks for pointing it out.

Also, the seed is currently a fixed value driving a randomizer. What is currently entered for that is a reference to a song by Tommy Tutone.
