Sorry it took that long, but issue of Happiest Day minigame not starting on Android version was fixed
It was caused by me forgetting that I left transition to the minigame disabled, due to debugging I was doing, which caused the game to stuck on Night 5 minigame
Thankfully no progress loss was caused, and you can now just replay night 5 and Happiest day should be working now

Thank you @TheGamesEx for finding this bug!
