I have been eagerly awaiting the full game for this, but it seems to be stuck "In development" for simply ages. I am therefore very leery about purchasing it in the current format. Is there anyone who can update me please?

You are probably the only one!
The photos are enough for me to know that I don't even want to get this game together with the necessary hardware as a gift. The photos show me that characters and objects in the game do not fit together and thus no coherent picture is created. The graphics seem to be randomly thrown together from different graphics sets. The hardware requirements do the rest: The game will probably not even run on a new computer with an AMD Radeon RX 6400.
I'm sure: This game will fail miserably!
