yep, i definitely will come back to get more endings : )
[SPOILER ALERT]
Ok, I'll try to give some hints without revealing too much! :D
Basically, the alien coins are the key for three out of four endings.
Apart from the "normal" ending where you escape through the well, you can leave after collecting all of the coins; or access (thanks to them) an otherwise inaccessible place, where you will face, uhm, someone.
At that point, you will have two more options on how to end your quest: one blatant, the other one more... creative! :D
Hope this will help. ;)
cool thanks a bunch i think i understand how to get another ending now, also does dying by night time count as an ending? you said you need those coins for 3 out of 4 of the endings so i guess not
update: i now have only one more ending to go, i've got the well/normal ending, the other well ending, not really sure what the endings are called but i also got that ending where you choose the left staircase
Uhm, you probably mean the right staircase... Since the left one descends back in Lockwood, simply allowing you to get the basic well ending.
The fourth ending is a bit hidden. It implies that you don't choose any of the alternatives proposed by the hooded man. :)
Nope, the night ending is not considered as an ending: it's just a different kind of death!
