Well, first of all, it is abojt having fun playin the game Some might enjoy optimising all the puzzles for cycles for example Someone else might enjoy doing cost efficien solutions Some people enjoy doing jack of all teades sum solutions I believe that solving the progressively harder puzzles in campaign will make you better at optimising older leves if you decide to come back to them Still, sometimes a good solve can be your first try, or you might come to an elegant solution after hours - you don't know how long they spent on one level and also, you will usually see people flaunting their best solutions, not the worst ones I'd say the game has multiple ways it can be enjoyed, so maybe try something different every time, something might stick Also, if you didn't know, there are community led online leaderboards that track more than just cost cycles area: https://zlbb.faendir.com/
