How to change the Game Type?

Previously, there was a career mode, but it was not working and it was cut for better times

@zeropol You only spend money each time you build tests, but it's just the amount you spend without the balance (I mean no exchange).

"the player's profile still works with career." ?
Although it is not possible to create a new game with career, career still works even if the game has been updated (I have reset the game so I am no longer in career mode).

What there was a career mode ? :D
How to you earn money ? What are the features ? Could you upload your save ( sandbox ) so I can try to load it, if you say " the player's profile still works with career." ?
edit : I found nowhere mention on career mode on the 0.7.0x changelog blog posts

hmm, Waiting for a new version...

@zeropol @sflanker I played career mode in version 0.7.x before, then disappeared, but the player's profile still works with career. I recently reset the game.

At the moment I believe the only game type is "sandbox." Someday there will also be "career."

There is only sandbox gamemode at the moment, sorry :)
( Me too I'm waiting for the career mode, but I'm not sure it is a priority. Last time I checked it wasnt on the roadmap )

@SelectAKey I mean the Game Type mode
I forgot

what?
