Thanks to the community for all the feedback, improvements have been made to the user interface.
Due to some some some overachievers, I hurried up and added leaderboards and expanded the max level allowed in the demo. The current plan is to keep the leaderboards from the demo and continue them into the commercial release.
I have many more improvements and fixes, as well as other game modes to add so I'll keep it brief. Thanks for all the support!
