The goal is to feed 10 vampires with unique blood and do it as cost-effectively as possible in order to score more points at the end. The blood composition can be checked in the lower left device. The remaining five devices purify or, conversely, pollute the blood (depending on who needs it). Let's start with a simple one, the central device from below mixes 2 substances, for this you need to put 2 flasks with substances that you want to mix into it (you need the flasks to just touch the device, then they will automatically fit into it). The device on the top right cleans the blood from infectious diseases, for this you need to put 1 jar in it that you want to clean.
The remaining 3 devices separate 1 substance from the first flask into the second, that is, if you put the first flask with substance A and the second empty flask, then at the output substance A will lie in the second flask and will not be in the first. If you point the cursor at the screen of each of the devices (a black rectangle with green stripes), you can see which substance will be extracted, but each of the devices has 2 modes, for example, the upper left device, a centrifuge, can separate both hemoglobin and plasma. To switch between modes, use the buttons on the device body (they are next to the screen).
We will be grateful if you play again and maybe change your opinion about the game for the better (sorry if it's too formal)
