Hi! I've played this game for a year now, maybe a little more, and now that I'm constant in it, I noticed that there's always a lot of boxes but never enough keys.
And because you need 3 keys to open 1 box, they tend to accumulate and actually never get opened

Of course I know that some of them is going to disappear, like a normal game but.. I think that this is too much (I even merged some of them!)

Perhaps increase the spawn rate of keys instead of boxes?
IDK, but it would be awesome if you could review it 🙂

Thank you!
