Where’s the key to the cells on level 2

Okay, I think I figured it out through trial and error and some experimentation with save files. Once you

step on the plate at the start of level 7,

the grate at the start of level 6 will raise and you can get back to the higher levels.

Notice that merely

visiting level 7 through the basement stairs or falling through pits

is not sufficient to raise the grate at the start of level 6.

This should be a complete list now:

It has levels 1-10 and lvl 13.

The number of secrets seem to vary, but here are the numbers:

• Level 1: 3
• Level 2: 6
• Level 3: 8
• Level 4: 8
• Level 5: 7
• Level 6: 12
• Level 7: 9
• Level 8: 6
• Level 9: 4
• Level 10: 6
• Level 13: 2

This gives 71.

That should be all the secrets found, if I've written the numbers correct. GameBanshee now states it has 70 of 71 secrets, but I've gotten it as 71.

The secrets are counted such that if there is a secret on level 4 that can only be reached by dropping in a pit from level 3, it is counted as a level 3 secret, not a level 4 secret.
