This is great, love the concept and the connection to the theme.
The art is super cute.
My only feedback would be to make it a little clearer on drag/drop when you are able to connect things (it took me a minute to figure out how to make any keychains), and maybe some music/sfx.
But other than that a really cool jam game, I loved the PC interface too.
Btw does the shop every actually open?
