On time, the developers (people often call it Dev) hand over the demo version. At the same time, the first concept art is urgently completed to put into the demo version if it passes this test.
The first big problem arose, the control part of the game was not as expected. Because control is a very serious problem, we decided to have a meeting to choose better options. After the meeting, we settled on the two most viable options from playing around with and analyzing the first prototype.
And the Devs plan to need 3 days to build the next two versions with a new control interface according to options A and B.
