The main problem at this level is to get the required number of visitors in the minimum amount of time. According to my observations, the presence of buildings before the opening of the hospital slightly increases the flow of patients. Therefore, I tried not to turn on the fifth speed from the start of the level, but increased it gradually:

• Level start: 1-st speed
• After hospital opened: 3-rd speed
• After psychiatric ready: 5-th speed

Thus, by donating some real time, I saved game time and was able to get the required number of patients by the end of the second quarter. Also, I tried lowering the prices of the services and putting in a few plants, but I'm not sure if this had any effect on the flow of visitors.

Run was made on version from GOG.com (on DOS Box).
