Its finally time to draw this self employed gamedev journey to an end. Its been five years of learning to code and design games but there is no way I can go on working alone for no proper income. No studio will hire me. That's enough now.
Thank you to all who interacted with me and shared advice and insights. Sadly not all of us have what it takes to make a success of it on the game development business. Its the Jobcentre for me Monday. Hope this degree is worth something.
Found out you can turn off the graphics smoothing in Indiana Jones and the Last Crusade on Steam. Go to Registry Editor and find the Lucas Art folder. Usually in one of the user folders. Then in the Indiana Jones folder set any settings you want off to 0 and if you want to turn them on, 1. Now enjoy the full nostalgic experience in all it's pixelated glory.
