I like the bottle spin mechanic very good use of the spin to win theme and a very satisfying sound design for the bottle. I loved the sound for when they're talking.
I think the music is perhaps a bit too short of a loop and gets repetitive quite quickly.
A bit of a tutorial within the game and some cues for the player may help as it wasn't super clear at first what was happening during the other character's bit and how long it would take to get back to the player's turn. It seems the bottle applies an effect towards a player each turn, perhaps randomly selected or perhaps based on where the bottle lands on that player.
There was also a few visual bugs with the dialogue text repeating itself or cutting off in some places. Slowing down the speed for the text that is displayed may help there. Also making the text larger and better contrasting colors could help with the readability.
Overall a solid idea. The execution could use a few more finer touches but it is a cool and creative take on the gamejam theme.
