The problem RPS on flow solves

It is a simple play-to-earn recreational game where users can earn and bet tokens among themselves

Challenges I ran into

Working with cadence was a little bit challenging, I just got to learn about cadence about a week ago, and it's the first resource-oriented language I have worked with. The access base capability model was also strange to me, i was actively looking for a type of msg.sender functionality to work with. I also had a problem listening to events using the flow client liberty, I had to listened for changes on the block chain by sending requests every 5 seconds
