I like that the limiting factor here is time. I would like to see money have a bit of an expanded role but I really think you should keep the key resource time as the name suggests. Also more options as to what to do with your time could be kinda cool. Perhaps adding a gambling mechanic somewhere to add some risk and excitement with cash and time, with rewards being more than just cash, such as research more time, accelerated time, or some other kind of buff or even a nerf. Another cool addition would be a collection of minigames to reward active play in some way. I think there should also be a much larger market place as well as many more achievements to acquire those upgrades. So far I really like what you've made and think this could eventually grow to be one of the huge ones out there such as adventure capitalist if some more content is added.
