I quite like the game, but this is bothering me to no end.
In the game, you can increase the, “efficiency,” and, “job speed,” of workers.
Job speed, as it is presented, makes sense. The proportion of materials used stays equal to the materials produced.
(If you increase the job speed, it may go from 0.5X/s used and 0.1Y/s produced to 1.0X/s used and 0.2Y/s produced.)
The increase you buy is one in power, as defined in physics; the process can more quickly convert X to Y, but it still uses 0.5X for every 0.1Y produced.
Unfortunately, when you buy an increase in, “efficiency,” all that it does is make the process more powerful, (e.g. faster,) just like, “job speed,” does.
Power /does not/ equal efficiency.
If the process were actually more efficient, then the /base cost/ of materials would decrease, while the /amount/ of materials produced would stay the same.
That way, it would actually be efficiency increased, (the workers’ ability to convert the material without waste,) and not their power, (the workers’ ability to convert materials, faster,) that was improved.
(Thus, it would change from 0.5X/s and 0.1Y/s to 0.25X/s and 0.1Y/s.)
For Heat, as is a resource with no cost, you could instead slightly increase the amount produced, by a proportional amount.
Please, for the love of whatever it is you hold dear, change the game to reflect this.
Please.
(Great game, though, very fun.)
