I've started playing Cube Farm a year ago and joined the beta testers. Since then I've been able to watch it grow from a good game to an amazing game. The developer keeps close tabs on his community and takes our feedback into account when deciding on future development as well as quality of life and ui design improvements.
Cube Farm is an amazing little game with a really simple and well designed core, enjoyable meta and succeeded in being fun with small and large time invested as a player.
I bought the online mode for a small and reasonable price and being able to compete with others in park and arena as well as personal challenges only made the game better but playing without this feature is still a worthwhile endeavour.
10/10 would recommend!
