It's a cool and unique game but the clicking mechanic is a bit janky. I got the secret ending and the uninstall the app one but when I wanted to play ping pong i just couldn't open the game. I click on the play image form all angles with or without double click but I just couldn't make it play. I think you should look into it.
Another thing that I dind't like are the restrictions on the text input. I think you made it so there sould be only some kinds of input like hello, hi, good, bad ( you could have put these input and maybe a message for non recognisable text like I don't understand you or can you repeat) it would add life to communication.
The other aspects of the game were awesome. I really liked the feeling the clicking and typing noises make it was a good call.
