I'm really loving the game so far!! One thing I've notice is it’s sometimes hard to tell whether an achievement has been unlocked, particularly when the badge is grey or silver. Adding a clear visual indicator (for example, a small tick) or showing the unlocked status on hover would significantly improve usability. I’ve put a rough (I'm no UI expert lmao) example below to illustrate what I mean:

Thanks for all the amazing work you've put into this game. :)
