Thanks for the feedback! I'm definitely aware of this issue. I'm actually working on an update that adds more content and more things to do with the resources, but it doesn't solve this problem completely. I hope to add even more stuff in the future!
In this update, for example, there's a new one-of-a-kind wonder type building that costs a ton of resources to buy and to build, and it gives a lot of score. I also added an option to convert resources.
