Thank you for your feedback, it is much appreciated!
We are currently working on implementing a save system, and things are looking good so far. I'm not going to promise anything, but there might be a major update coming at the end of next week. ;) It'll also include some adjustments concerning the survival mechanics and a little "extra" treat in case players are struggling to survive. Leave us a follow and you'll be noticed as soon as the update drops.
Aside from that, many thanks for your kind words, it means the world to us and keeps us going!
