Thanks for your feedback!
We initially planned to design a game that you can play together with your friends and not alone. As you said, especially in times like this, where you cannot meet IRL.
I can only recall that there are book/tv-show guessing games using emojis. I actually haven't searched for similar games to ours. Anyway, "What's in the box" got heavily inspired by the Jackbox Party games - that is creating and joining rooms, round-based gameplay where all players can do something.
Yes the bugs... You probably know it best at first hand, lack of human resources, limited time and little play-testing 😅. The thing with the emojis is, that it's up to the browser how to display them. Some do it correctly whilst other display them as separate symbols or not at all. Not to mention that emojis are displayed differently depending on the font, browser, OS.... That adds another layer of flakiness on top 😄.
Finally, the dragging. I guess you should not depend on 3rd party components - lessons learned. Also, dragging does not work on mobile which is rather sad. Unfortunately there was not enough time to fix all the issues...
