Thank you so much for doing a letsplay for Gulam :D I'm so glad that you enjoyed it and I'd love to see some more episodes!!
(For endings there's at least 4 other endings which doesn't include the "true" ending. If you want to reach a definitive conclusion/the true end you'll have to get one specific ending before you can get the true ending. I'm not going to spoil but if you can't get it or another ending please tell me and I'll be sure to help ^^)
