Why does it take so many clicks to start a custom game?

Reborn Gem TD is really hard, so I have to restart a lot. To do this takes at least 3 minutes, which is ridiculous.

1. Custom games
2. Library
3. Create lobby
4. Start game
5. Accept match
6. Wait for loading screen
7. Lock and start (again)
8. Wait (again)
9. Another loading screen (again)
10. Wait another thirty seconds for no fucking reason

Who designed this shit? TPS reports inventor?
