Great game but constantly freezing! – That Memory Game A Memory Matching Game of Concentration Review

Love it for myself and my preschool class, but every single time I close the app and then go back to play later, it's frozen. I've deleted and re-installed it several times because I'd really like to keep it. Would be great to have this fixed permanently; I've never had this problem with any other app.
