Improve hints for level 26

[maAPPsDEV]

I suggest giving more hints for level 26 - DoubleEntryPoint

It was really impossible to figure out the issue until I saw the level factory.
Once you know that, the solution would turn to school work.
It is because the goal of the level is confused much:

• do I need to drain LGT as well as DET?
• do I need to transfer tokens to someone else that is not a sweptTokensRecipient?
  These questions were what I tried to get answers to.

You should hint that sweptTokensRecipient is the player himself or should explicitly explain the goal i.e. "don't allow to make DET balance to 0".
