TitanGamesStudio is consistent in games and completely lacking the ability to replay the game from the beginning. I would have rated higher if I could have deleted my saved easily from the menu.
Got to love the investment risk! It's the risk of success, since the principal is returned even if it fails. "Teleportation? Sure, that's got to work, here you go." "Pyromancy research? Who doesn't like fire? Have quagillions of gold and honor.... but return that if it doesn't work out."
Great game!
The physicist in me has these suggestions/comments: speed implies velocity, so a button press or click does not actually increase speed/velocity, but will "advance" the tick position by a percentage. Also, the tick speed is really the tick time, since speed/velocity would be its reciprocal. Admittedly, we all understand what you mean by the units, so they probably are not worth changing.
I'm not sure which is most disturbing about this town, the number of fires the citizens light, the bad driving, or the suicidal pedestrians that walk right in front of a speeding fire truck.
