Great concept with a lot of potential
The interface is poor, the main screen should include the following:
1-My team tab/ when pressed I can see my purchased players and should include more room then five so I can get some bench players.
2-A players market tab/ when pressed it shows list of players with each having a main role where his highest state is and a list of his 3 main heroes for that role, and a search toolbar so we can search by role or by hero.
3-a settings tab/ when pressed you can find sound options and some other features that can be added like adding friends and some general settings like saving current game and renaming the saved game
For the players:
1-Add a picture you can find those in Google very easily and it give a simple upgrade to how the game looks
2-Separate the stats into different groups like stats, mental skills, physical skills, lanes, positions and player information, make it a bit more colorful maybe
For the gameplay:
1-Add a live playing mode small map white icons moving around like dotabuff small map with heroes icons and make it a live active map during the game that shows what is happening and fix the speed of the game and add more features to that.
2- Add some music from dota or just a general war team music and some sound effects for clicks we make
I can suggest more but these would be a good set of upgrades I think to make the game much more fun.
Best of luck
