you have taken the context of a rogue-lite, and so very elegantly set it in the context of the theme of generosity; and there is so much depth in the system-design; an asynchronous co-op with everything recorded so you can see the impact of your choices; the trade off you make - sacrifice a part of yourself to help another player like you later + a meta layer of connections which is visible - it's a tightly-woven, well-thought out system.
I was a little skeptical in the beginning because it looked like a combat game ( how can it do justice to the theme?); but this really, really works
very well done!
