When I bought this game on Steam for $15 it would crash whenever I started it which probably had to do with my computer so I never got the chance to play it. About a year after that I found out it was available on the 3ds eShop, where I downloaded and it actually worked. Many people give the 3ds port bad rep because it "crashes a lot". It's only froze on me like 7 times but I don't notice since I've come back to the game like 1000 times and still do. It has incredible replayability and to this day I still haven't gotten every power up and have only beat mom twice, once with Lazarus and once with Azazel. I still find myself coming back to this game very frequently.
Strangely enough I remember this game from when I was younger as well but I could not for the life of me figure out what it was called to this day. You sir made my millennium by mentioning one of it's characters in one of your Youtube videos; I adore you for that.
