Time required to make a game and is it possible?

Can a cross platform game be made with Thunkable? 1v1 Multiplayer game, It would require FB for sign up and would have two movements. How long would it take to develop? I am new to Thunkable and have also no experience in game development.

It’s possible. See the Game 1 and Game 2 screens in the project https://x.thunkable.com/projects/5b5865df01f90009ea99f0b9/project/properties/designer/

The creation of the game will take 1-2 months.
