Your decisions mattering is a talking point of nearly every RPG Maker horror game in existence so I paid it no real attention when reading it, but it's actually true here. As I was nearing the end of the game, it really did feel as though every decision I made weighed heavily and carried great impact or influence in the 'universe' so to speak.
I'm an optimist at heart, so some dialogue was difficult for me to get behind. For example, there's no way that I would still be with our 'partner' for three years. I don't support that level of negativity where people opt to see the world through a lens in which only the painful undesirable things exist. I'm not so naïve that I believe coexistence or even just existence for that matter, isn't an incredibly dangerous and unforgiving experience; It certainly is, but it is also everything we have. Humanity has consistently improved the conditions of its people despite the setbacks of war, disease, or hubris. This is how I feel about the human condition, even with all that is going on. We are resilient and will make it through as we always have for millions of years.
That being said, any game that can draw out such a deep and philosophical discussion is testament to its genius-level writing. I can't wait to see what you do next!
Thanks for making games!
