Edit: this links to only a tiny portion of the post mortem.. i jumpped the gun a bit… they will post the full post mortem in the next few weeks
last month i did a very in depth postmortem on the development of the Binding of Isaac, it might not be a read for all fans but fellow devs might find it interesting.

i got to make the cover of the magazine :) sadly peeps floating eyeball seemed to be a little too gross for the cover so it was covered up by a tiny ingame sprint of Famine and Loki :)
ill post the unedited cover as well as a time laps video of me drawing it tonight!
