I think this is an app not a game ..
Hi, I remember this app that I used to play since 2024, it was vertical and you could chat with other people, you could upload images of charachters and thay would react by these emojis that you had to upload (😂😃😅😭❤️ I think) when you clicked them in the game the charachter you uploaded would react. For example the heart would do bubbling effects and have hearts showing. you could walk around the lobby and talk with other people as I said before. I remember that the lobby looked like a playground where were trees, slides, trampolines etc. The charachters were 2D and it's not like I remember much about it :D
I would find it helpful if someone found this game/app or knew about it because I really want to play it again and this is something that randomly came in my mind, I've tried to ask a couple of ai's but none found anything so it's my first time trying Reddit.
