Alright. Now this is getting weird. Apparently...there's a whole story with some kind of "otherworld" and you have to unlock the powers? In the version downloadable from this site, like you get the powers for free at the beginning and there is no "otherworld" apparently there's an entire story here...
I'm obviously missing something here....
Long story short: In version 0.8.2 and previous, there was an area called the Otherworld, where Peter (MC) would meet Neala (red head with freckles). The two of them would be... "Friends" (allied is more accurate) and try to solve the Otherworld together.
Nergal disappeared and decided to remake the game from scratch (in terms of story) when he returned, but for the time being, the Otherworld is removed (it will be re-added at some point in the future, likely version 1.0).
If you download an older version, you can access the Otherworld and interact with all characters missing (Donna, Neala and Kaylee).
