Thanks again for the super kind words.
Sorry, I worded that wrong regarding the location. It WAS in North America, but I then shifted it to Scotland and reworded a few things and changed a few sprites. I even included a nod to my father's side of the family from Scotland, but that's a VERY subtle reference that no one outside my family would get.
Your input on the desert crossing puzzle is excellent. I love hearing feedback like this cause it lets me know how to approach puzzles in the future. The third game is actually a much bigger project and a joint effort with a small studio, but it's still a secret as of now, so I can't say anything else other than it'll still be a humble NES-style MacVenture, just a tad more ambitious than the last two. We're planning on announcing it sometime in the New Year and it will in fact cost money (no amount decided yet) and it'll most likely get a wider release as well as here on itch(.)io, either through Steam/GOG or even console (fingers crossed)
Thanks again for all of your comments. Let me know if you have any other feedback, it's always welcome and I can't wait to share the 3rd game when it's announced!
