That website you linked doesn't lock the viewport so on my phone it's constantly panning or randomly zooming
And the grid instead a keyboard layout actually matters more than I expected for how easy it is to type
Having to manually start a game is a tiny thing but doesn't feel as smooth
I'm looking forward to trying to implement these subtle animations, too.
Not to belittle your effort, but one of the appeals of Wordle is 1) everyone has the same word, 2)Once per day. It becomes a ritual between friends.
