You were very thorough, thank you.
>I believe I completed all the quests, but the QUEST menu bugged out and is no longer available, so I couldn't check if I missed anything. From the top of my head I remember: Boy, Boy Ball, Cocaine Elf, Ghost Gun, "Main Quest", Crab Hunter, Keylogger(ish), Defeated all the enemies, including the post sign and the bastard.
You got all quests that are there at the moment. I have no idea what the quest menu bugging out means.
>The Keylogger quest, after I finished the Ghost Gun, I went back out of bounds, and talked to the NPC but nothing happened. This might be bugged.
Not bugged, just not finished ;_;
>The Crab Hunter, I don't know if this one bugged as well. It told me to defeat 6 crabs. After talking to him again, he tells me the quest is completed, and talk to him again to hunt bigger crabs, but nothing happens.
Yes, its content that has not been done yet. Essentially, its a second counter, then after that quest is finished there will be an additional area opened with a optional big boss.
>I feed the cat around 84 pieces of bugless catfood, but nothing happened. I don't know if anything was supposed to happen.
Bugless catfood speeds up the animation of the cat, bug catfood slows it down. Sorry that you put so much effort into just this, its kind of a one-off joke. If you eat bugless catfood, your movement speed is increased though, and lowered with bug catfood. Guess I will add something for feeding him multiple times, its a fun idea.
>I got the snake from dicegobo, rolling a 14. The keylogger NPC told me the witch would want to buy it, but nothing happend when I talked to her.
Yes, stuff that is not finished yet. You may have noticed transparent snakes appearing quickly once you enter some maps too, this will be some Animal Well/Fez shit once its done.
>I got Spaceship parts A,B and D. What do these do? They change the endings I get?
Preparation for an ending that is not in there yet.
>I might play it more to get the other endings. Overall very good job!!
Thank you for playing, an easily obtained ending can be gotten from jumping into the hole in the forest. It is not properly labelled as such yet, but it will be.
