It only took me 40 minutes to finish
The story is brief which is GOOD because it doesn't have a lot of pointless details (i.e. lots of gameplay you have to repeat in order to get different endings, scenes solely included to show character traits that are repetitive or disrupt the flow). However, the briefness is also bad because aspects of the plot and the characters aren't explained--they just are.
For example, the characters' motivations are just briefly stated and not totally explained. Arguably this is: 1. more realistic (IRL people don't explain the deep inner reasons for their actions), 2. again, a way to avoid pointless detail (yeah, there could be a more detailed backstory behind what happened, but there doesn't have to be one just for the sake of it. If it can be summed up faster without losing much effect, then that's arguably more efficient.) 3. what happens in stories with much explanation anyways (even if you dedicate a long section for backstory for a character, it often is just a series of facts or a summary of the relevant parts anyway. So arguably, that long explanation is not actually too different from a briefer summary).
