Some games name their levels (like "Level 1: The Beginning" and "Level 2: The Struggle"). In this very specific case, "Level" would be part of a name. However, I know that some people refer to levels as "level 10" or "level 1" when it is not a proper noun (e.g. "I beat level 1 of Super Mario Bros", and your example as well). I think that there was a misunderstanding on my part.

In Hay Day's case, it seems, "level" would not be a proper noun, since they don't name the levels themselves. I capitalized "level" whenever I saw it in the wiki's articles because I assumed Supercell named the game's levels.

My preference, then (since grammatical rules don't apply here) is Level, mostly because the game capitalizes "levels" like "You are now a LEVEL XX FARMER".
