Heya. It's Randolf. You've made something quite beautiful here. I feel like I've seen this exact concept before elsewhere in the nooks of itch, but I can't quite recall. Nevertheless, great job. The idea is strong; quite literally: a mechanical interpretation of 'reading between the lines.' Standout. From a story standpoint, my only real comment here is that there lacks a bit of foundation, introduction, explanation. These aren't required in any story per se, but when you want to hit a narrative pay-off, you have to first establish towards it. I want to be introduced properly to our two characters just a little more for me to care deeply about them. Maybe that's just me.
From a gameplay standpoint, there isn't really a reason for there to be a maximum of three clicks(?) I don't know what you guys had in mind when implementing that, because at most I miss out on like one or two words per postcard. Is there like a different ending if I press the right words? Don't know.
Anyway, great job again. Loved this short experience. Congrats on participating, and I wish you three the best.
P.S. Get in touch again sometime!
