Wow! Thank you so much! I'm so glad you could play it on an original gameboy and for it to be somewhat close to the intented experience, I got a kick out seeing it on hardware. I ran out of time so a lot of features got left out/unrefined, but pressing Start brings up a map that shows where you are and which cardinal direction you're currently facing (though it might be harder to read without colour), as well as any soldiers you've already found. The Select button brings up the inventory where you can also get hints for soldier's whereabouts, but that's as much I could get in there of my intended clue system. I see you also submitted something, I'll make sure to play and rate your game when I get home!
