Please focus on making a great game and not only on the skins, don't let it die as fall guys.
We don't have any party game that survives through time and I would love too see this game make a big success.
For ideas you should consider, my biggest suggestions would be:
1) Daily quest, so everyone can make a few cookies.
2) New maps and different game modes, I know you have too see if you will implement seasons, just don't wait too long
3) hear the community, and fix the problems that the game have
Thanks for reading this post I hope anyone that replies to this gets more ideas of how to improve the game and don't focus on just skins. Make a good game and you will have more money so good luck and have a nice day.
