Do be honest, I don't know. Your game does feel good already so now it is just a matter of content and polish. Check out our movement game at this jam, maybe? Might inspire you for something, I hope.
Anyway, you have a strong vision for your game. You know what you want it to be, so any new addition will be either perfect or pushed back for better. Just don't lose it in sea of feedback you get and will get in future. Will love to see your game shine.
