probally not working on major update. He is doing it with ink and ink is like a programm langue for beginners that want to create a text based game. However you can rlly fast code with it. I tried to do a fangame with it and the Demo only costs me 1h and 30min. and the first update only the half of the time. My game is probally shorter then just one update from this game but still it dont takes 14 days to create a major update for the game. But its probally not abdoned. Probally a hiatus from the updates.
