Thanks for playing Geminimax! I'd really like to add a background, although not really sure what fits. The ending part was just something I got from watching open ended movies, lol.
I think your copy of the game is bugged out as there should be a death animation of the NPCs when you shoot them. For the dialogues, I'm still bad at it. When making the game, I also feel that the dialogues are a bit off too.
