This gave me strong Leisure Suit Larry vibes, definitely reminiscent of those classic Sierra titles. Really cool that you built it in your own engine. I peeked at the file structure and saw lots of .groovy files, Java jars, and custom assets.
I gave all three levels a shot. In the first, I managed to insert the disk and USB key; didn’t get much traction on the Boris level; and in the Indiana Jones one, I picked up the pickaxe but couldn’t figure out what to do next. A hint system would be great for casual players like me to enjoy stories but often get stuck.
