When I start the game I gets a black screen with some UI. I can do nothing, then press TAB to see some controls, but there is nothing about how I can start the game.

I'm sorry to hear that, it appears the build you've downloaded is the one from the Itch servers, which is a broken build...
If you still want to try the game, you can download it via the dropbox link provided in the description.
Or better yet, you can wait for a couple more days, I'm working on polishing the game and I intend to release it here for free.
I'm sorry for your inconvenience and hope this reply clarifies things.
