Thank you so much for playing the game and I'm glad that you enjoyed it! :) Yeah, the default ending is definitely set up to leave a lot of questions unanswered. Have you tried to get one of the other endings? Once you get on the path to the other endings, a lot of the unanswered stuff will start getting further fleshed out (hopefully eliminating any confusion from the default ending). Whether you do or not, though, I'm really appreciative of you playing the game!
