On the off chance you're reading and you want to pursue more IF, allow me to suggest the following really exemplary works of the past decade and a half which require only a modest time commitment of perhaps 1-3 hours. (Of course, there are many more; a lot of the best IF is more in the 5-10 hour range, depending on how broadly you explore the possibilities and/or how good you are at solving puzzles.)
