Please do not remove the game and reupload a new version as a new game without a very good reason. There is no need to have the version number in the project title either. You can have updates and devlogs on one project page. Even different versions, if you are below the size limit.
The game will be removed from any collection by doing this. Peopl can put games on collection in browse to look at them later. Also, if you change the link, any bookmark or outside linkt to it will be invalid.
The screenshots look nice enough, but I have a huge backlog of games to try out. I only noticed that you did that, because I could not find you in my collection and my browser history pointed to a different link that now is not accessible.
