HypersomniacLive: On the contrary, your input is more than welcome. When you say "rather short", how short would that be? Hopefully not "it ends right when you've started getting into it for good" short.
Well, to tell the truth I haven't completely played through it, but it's split in chapters and I think I have already seen 60-80% of those, within about 3 hours, and I usually spent 1.5 to 2 times the amount of time on a game that the average users would need. Howlongtobeat.com says the average polled player needed 3 to 3.5 hours to complete it.
I think that's perfectly okay for the type of game it is, I mostly said that in comparison to Fran Bow which takes 8-9 hours to play through. Personally I wouldn't pay the regular price for it, but the IGS offer is a good deal, if you like these kind of games. It's well done, just not all that memorable on the whole, IMO.
