Sorry - I was not precise.
I have played the game with a friend now and we have problems to exit the game - I miss an exit option as part of the menu - or just pressing Esc in the menu to exit the game (maybe with yes/no dialogue).
With Logitech F310 the left analogue stick can be used to steer but none of the buttons has a function. Would be nice if A (and X) were similar to space and Start same function as Esc (to invoke the main menu).
We encountered a bug by pressing Esc during the tutorial being stuck in a black screen with mouse cursor and music playing (i.e. no menu appearing).
It is really impressive what can be done in such small time.
