The giant's jewel mining game seems to be broken, but only some of the time. When there are 4 or more colors in the ring, clicking when the arrow is in the correct color gives me a failure. If it happens once, then it will fail for the rest of the game (and also play the "fail" sound when exiting the game). This only seems to happen half of the times I try the game, no idea what is different to cause the error. I'm on macOS 10.15.7.
I'm also seeing a LOT of typos in the English dialog - too many to list here. It's not a big deal as I can figure out what is meant, but you might want to have a proofreader go through all the text at some point.
