A simple medical simulator set against an HP Lovecraft backdrop. Has a simple gameplay loop with a pretty forgiving difficulty curve but the winding plot and cute art style made it quite fun.

Overal. I really love the game, atmosphere and mechanics BUT, they messed up the daily timer so much. Even with the addition of the 'chill mode'. When you start this game up, immediately on day 1 the clock starts ticking before you even properly had the chance to read through the instructions, there's a daily newspaper you can have a look at while your first patient is already knocking on the door. Could be me, as a non-native speaker who needs a liiiittle bit more time to soak everything in, but I feel punished for it. Now the choice is either 'chill mode', which i feel takes away all the timepressure and the real tension of the game or the 'classic mode' which is just too stressful. At least don't have the counter slow down at times when your patients and or leave the room or something or only count seconds when you actually flip a page in stead of just reading it. i'd still say the overal experience is positive though, but it won't make me do another playthrough

This game is mostly math and logic disguised as lovecraftian horror doctor play. Now, I like that, so I can wholeheartedly recommend it, but if numbers such as 5 (or -5, the highest and lowest truly relevant numbers that may appear in the actual math) and divisions by 2, 3 and 4 are too much for you, then you may want to steer clear. You may also have to look at a circle sometimes and make boolean decisions. If that has not deterred you yet, this game may just be for you. To sum up the game, you are repeatedly confronted with a random number between ]-3; +3[ and your general goal is to bring that number to +3 (unless you have some story or achievement related reason to get it to -3). In order to do that, you are given four different variables that you may fill with numbers between 1-9 (not a number in the actual math mentioned above); later in the game, you may even need to fill several variables at the same time (it is called "mixing"). Then you try out the effect on an invisible function to see if you get the initial random number to +3 - of course, you are given plenty of hints as to how the desired result of that function may be. If the result was good, you can just repeat the process using the same values for your variables until the random number is +3 (the closest thing in the game to multiplication), otherwise, you may need to change the variables a little. But watch out! You may be eaten while you are doing math. Also, there are ghosts in your head and you need to find them, otherwise, a dark, oily net will prevent you from using your variables until you drink your illegal drugs and alcohol cocktail (not illegal yet in the era in which the game takes place).

The game is a fantastic premise and the puzzles are really engaging - On Classic mode. Unfortunately chill mode is extremely boring. Though the game said it just removed the timer (this is what I wanted) - it also removes ALL of the difficulty. This means all interesting parts of the game are stripped out, including all of the eldritch symptoms that are the core of the game story. I even got the exact same medical puzzle five times before giving up on my run. Classic mode's timer ruins the game for me, as the stress is just too much. I'm glad I have my partner to play for me so I can still enjoy the game.
