It's easy enough to fit a game like this into a single play session because of its short length, but it's also hard to just simply want to keep everything to that extent given how bleak everything in INSIDE shows itself to be. Yet it's also that simplicity of the game's mechanics that ultimately make it all the more worthwhile.

The puzzles are simple, but as you figure everything out - what makes INSIDE work can only be best summed up by the fact that there's no clear idea what comes afterwards. It's the fact that there's no clear idea how this universe works that makes one want to continue on with the game, and the bleakness just makes you wonder where it'll all end up.
