In order to keep the light on you need to avoid Badeline in the starting room. Only from hitting her does she activate her guiding mode otherwise its assumed for casual play that you would blindfold yourself without Badeline guiding you.

I also forgot to clarify that you need to right click Super Meat Boy in your steam library. Then click Properties and in the first page (General) there should be a Steam Cloud section and you want to make sure "Keep games saves in the Steam Cloud for Super Meat Boy" is unticked

emm would you be able to explain exactly what you did?

no worries :)

if you can locate your savefile at program files x86>steam>steamapps>common>super meat boy>userdata (or wherever it may be on your pc, mine is there) all you need to do is copy the savegame.dat file and paste it somewhere safe. then you can remove your save from that folder, your game will have no progress and your save is safe for you to paste back in whenever

hey do you play on pc?
