Ahaha, the part where everything you touch dies was definitely partly inspired by my failures to keep some plants alive. There's been some that seemed to start dying as soon as they passed my doorstep. But it definitely feels rewarding when something works out.
I'm glad that the melancholy mood came across and that you enjoyed it :D It can be hard to tell if things come across like I want them to, so it's great to get feedback on what the experience of playing it felt like to you. :>
