I thought this game was well known but I haven't seen almost any mentions of it recently. It's very weird for a FOSS enthusiast not to advertise one of the best open-source games of all time so here I am trying to make it spoken about again.
Disclaimer: this game may be addictive for some individuals. Player discretion is advised. If you notice any symptoms of addiction while and/or after playing the game, stop playing immediately and consult with your doctor. Untreated gaming addiction may result in severe consequences such as digestive disorders, social behavioral disorders, loss of job, and depression.
Yes but that's the thing. The difficulty increase is probably one of the highest in the game industry and all levels except for the first ones are quite hard. Also this is not just from my experience. I read an article about it somewhere in the past.
I looked into Mindustry after seeing it on a pretty big gaming YouTube channel (Real Civil Engineer) and there was quite a discussion about it so I would say it's a very successful indie title in general. That's also why it's a perfect advertiser of today's FOSS (alongside with YouTube downloaders lol).
