I have been checking in on the game since a bit before Alpha 2, and the Career mode seems to be exactly what I was looking for! So far I am enjoying the progression of unlocking the different resources, logistics, etc via the tech tree (and I'm always a sucker for tech trees generally!). I like having a focus by being forced to use certain industries and to think strategically about how to unlock certain products. For instance, in my current playthrough I am currently working towards getting cheese in production and then unlocking further factories. I am also thrilled that I am now able to generate a profit! (I sucked at that in earlier versions haha!)
Anyway, I just wanted to let you know that I have been enjoying watching your game develop and flourish. This game is definitely up my alley (big fan of Anno, Transport Fever, Industry Giant 2 , Factorio, and basically anything with production chains), and I am excited to see where it goes. I also wanted to let you know that I really like the graphics style, and I very much appreciate that my ultrawide monitor (2560x1080) is supported.
Keep up the excellent work, and best of luck with the Steam launch! I will certainly leave a positive review when you launch!
