I beat Blueberry Garden...
after about 5 attempts. You get a password to a secret page on the developer’s site.
I’ll be vague to avoid writing a spoiler, but I’m kinda disappointed because I may have missed something at then end by doing something right before the fade to credits. Meh, probably not. This game was decent in a very strange way, but not real big on the payoffs. I mean content wise.
