Love it! But...

Great game. Lots of fun and relaxing! However.. Theres one level where it says theres a key, but theres no key that I (or seemingly anyone else) can find. Theres no outline to reveal it and its near impossible to tell where it could be as most of the shapes look like they could make a key. Its a tad bit frustrating. If its a glitch.. Hopefully it can get fixed. If not, hopefully we can get a hint.
