WOW THANKS SO MUCH FOR THE VIDEO!!!
First:The stress bar is for that avoid the enemies, you can touch them and if it's full you can keep playing and learn the level. That is the function.
Second: For the another endigns is:
-Good ending:Stress bar without full and without the dream Catchers(The circle at the beginning)
-Bad ending: with the stress bar full
-And the real ending: Stress bar without full and the trhee dream Catchers (The circle at the beginning)
Third: I don't knew how uncomfortable was the controls untile I saw you play (Altrough you understanded the controls pretty good). Sorry for my part
Thanks for playing and the feedback!
