In general, each session can have 4 endings:
- All values end up green --> token * high multiplier
- There are no messages that correlate to the current patient values --> no more interest --> token * lower multiplier
- Patient runs out of token --> token * 1
- One of the values goes into the red --> token*0.X (I forgot :D).
In general, you can fail in each session based on your choices during training, but given the current training set, it is easier to not fail.
The ultimate failure state would be to not have enough money for the bank, which is a bit easer as also a session that ends too fast will allow this.
