ID: 68B9-0000-0036-A704 Looking at this level, do you have any idea on who could've designed it? The dark mood, the rooms crawling with spiked enemies, and the multitude of hellish firetraps? Come to think of it, maybe it's a bit of a stretch to connect this level to Tom Hall, co-founder of id Software and one of the lead designers of Doom. The level itself is by no means the greatest out there (the guy specialises in first-person shooters, after all) but it's still fascinating to see what happens when you give the brains behind Doom some Mario-making tools.
