Holy mackeral! I don't think you will ever learn Inform 7, design and code a game and get it tested in one week. If you can, you're a better man (or woman) than me. Maybe ParserComp 2023 would be a more realistic objective.
I don't plan on learning the entire system inside and out haha, just the basics to get something working and functional before the deadline! Yesterday I played around with it a little, it's very complicated but I just use the things that I need, and ignore the rest, I'll come back when I need those haha
I don't really know how long are these games, on average, or really what style... I'm going with a kind of puzzly feel, let's see if I can reach 15m playtime! Until now, scripting new action has been the most fun thing to do!
