A video of me getting the achievement Brimstone Boy for anyone interested ^^
Only a couple more "iron boy" achievements left to go, but I don't think I'll be able to get them all 

My first full SMB chapter, complete with 20 levels using the Hell tileset. I know it's not the best decoration or gameplay wise, but for anyone who is still interested in fan-made chapters, I hope it is enjoyable :)

-The Binding of Isaac is obviously the theme for this chapter
-Bandages in nearly every level
-2 months (approximately) of building levels
I hope you take the time to check it out 

These are some really great levels! I've downloaded and played through most of them, and what I am amazed most by is the unique design of the levels (and the difficulty). It introduces several new concepts from what I can tell, and looks very nice.

It's a shame uploading on SMW is disabled, of course.
