you're playing an outdated version of the game :/ the most up to date demo is on Gamejolt, the dev stopped updating here, for some reason.
The game is also on Steam in Early Access as well.
Thank you for the descriptive update!
I really did enjoy playing the game, and can see past issues with despawning or errors in early development.
I try to introduce people to new indie games whilst giving the developers some feedback they might have missed, or maybe ideas for the game.
Definitely a fun little game I played, but at the time it did have frustrating moments to say the least haha.
I'll probably return to it some time once it is finished!
