I really enjoyed the game (demo) as long as I was able to play. Unfortunately, after 20 minutes the game crashed (with an Unity error pop up). After searching the forum, it seems that this is an issue other users experienced as well.
Consequently, I removed Forge Industry from my wishlist and I won't buy it (for now), which is kinda sad, because I liked the game so far. Might check the game's patch logs from time to time and give it another try, when the game becomes more stable.
Thank you for providing a demo to test the game beforehand and good luck with your future endeavors.
