Continue or Cancel Project...?

I am done with Squared Up! .. for now, I don't know what else to add.. so i have decided to make temporarily stop making the project and focus on more polished project, Slimy DELIVERY,  Squared Up! is a project made to test and post a project as a dream goal to finally share my projects to a bigger commuity, I ask of you if you want to contine supporting  this project, leave a comment or share this game with your freinds! so.. with that out of the way, I ask of you is how do i make a game loop for this project? I don't know how to end levels.. exactly so I ask of you of what end-goal you want this game to have.. so with that out of the way, I wish you a merry christmas and happy holidays! Yours Truly- Willis
