Spoilers: There is a boss. (Which can kill you.)
Come to think of it, I was actually a bit bugged when I came into this thread towards the start of my gameplay and found out that there was a boss at all. It's just one of those fundamental unknowns in a game of this style. I don't think that there's really anything that could/would be done about it in terms of posting, though.
But back on the subject: can I presume that the "side of the head" thing was brought up because the original poster felt it was a bug? I'm not sure I would call it that, myself. People who have a tenuous grasp on life, yet who like living, should refrain from standing close to giant moving evil things.
Alright, where's my ultimate prize?
That is so awesome. Congratulations. And that reminds me: even though you can't pick up this body, the game sort of records you as picking it up, so you can throw it around despite the illogic. I believe people have been noting this.
Some quick fanart from a big fan.
Also awesome, but what is that THING on the reverse side of the man-eating plant image?
And I might suggest NOT "fixing" the trees, because that actually gives stuff like the Climbing Gloves, Springy Shoes, and Teleporter some good value to them.
Likewise, I was worrying a little about how many obstacles this would trim from a level. It's like the platforms with ladders in the caves: the original style trees can be climbed somewhat, yet are still solid objects. If they are no longer solid, then what will stop the player? Will new obstacles be added to compensate?
