Thank you for you feedback, happy to know you liked the game.
And yes.. it's exactly like you said, figuring meaning of all emojis is a part of the game by design. However, we understand some people may not enjoy it so we added special spoiler section in the game's description with exact explanation for all emojis. So if you want to skip "figuring it out" part and just play the game and get high score feel free to read it :D
