It makes me really happy that you enjoy the game! I'm working on a pretty large project right now, so hopefully I'll have some updates about that in a couple of months.
As for the different endings, I haven't thought about stating how many there are, but I don't think it's a spoiler. The game has two halves which have their own endings. In the first half of the game, there are five endings: two good, two bad and one true ending. The second half of the game, which can only be accessed from one of the good endings, have a few player decisions that alter the ending.
I hope you enjoy your playthrough!
