I love this little game, it is fun.
I’d like to see more out of this game though, the buttons are a bit small, UI could use some work, and functionality like pausing isn’t implemented.
I got around 1,500 points on hard mode before my hand got tired of tapping the buttons every time the demand changed.
I ended up deliberately letting the coal run out, to save the score.
The game has no audio.
Mechanic wise, the game is really far ahead of anything else I’ve seen on the AppStore that is close to realistic in the simulation. I’d just wish it was a bit more complex. Perhaps you have to manage the damage of the steam turbines. Upgrades, money management?
Either way, the game is fairly priced, and for a dollar, it is worth it to check out.
