Good for a while, then you just want to burn it. I got to the end of the fourth season only consulting the walkthrough one or two times, but after that it just went insane. The plotline and "four potions" made no sense and there was little to no attempt to explain the plot significance of them to the player. The numbers only made loose sense in context to the game. I accomplished a lot without ever even really understanding what I had triggered to advance the game, especially with stupid little things like that candle with Prozac in it. The game frequently was unhelpful in telling you when you did do something right, as was the case with the four potions not directing you to pick up the phone in the first season. Overall this reminds me of Submachine, where the beginning feels intuitive and the end-game feels unforgivably abstract and senseless. Nothing was explained at the end of the game either, which made all of the psychological tension feel tacky and irrelevant.
Aside from that, nice job on the pseudo-3D graphics and sound, it's an attractive game.
