The entry for Glenn's quest is in a pending disqualified status on the following grounds:
The quest cannot be completed. Level 9 (left side) uses DMap 9, but Level 9 (right side) uses DMap 10. The quest relies on killing bosses on the left side, and having them remain dead when you explore the right side, but because these areas do not share a DMap, the boss flag does not persist and it is impossible to complete the level.
There are also several softlocks, but the hard lock (unwinnable game) removes it from this contest.
Further tests will confirm this issue.
Cancel. Cancel. Cancel.
This has been validated as winnable and is not disqualified.
