This is most unfortunate, the game certainly looked promising and I've certainly seen it evolve over the years. It always seemed like a massive labor of love and highly ambitious!
The dedication you've shown is amazing and the strength to call it quits is commendable too (I'm sure it was a very hard decision).
I hope the experience you've gained from this helps you going forward and leads to a (or multiple) successful projects. It's all we can do facing these setbacks, take the lessons and keep moving forward.
Wish you the best, and I'll be looking forward to your future projects.
