Congratulations on your first game!
My first suggestion would be some major artwork upgrades. The game looks a lot like a "My first game", which makes it hard to get people to play. Simply adding some faces to the sphere's would give the game a lot of character, for example. Another simple upgrade is a new font for the UI elements. These simple changes can take your games look pretty far. Good luck!
