Be carefull wit hthe SFX, they can be anoying if they are too loud. In the other hand, it was fun to play and you got elements that are pretty unusuals in game jams (that's a nice menu right there, and the local multiplayer is a nice surprise)
going to make sure the audio isnt too loud for the next time
for the menu I think about the halo 1 menu and with the unity animator I move and rotate the camera thought the game scene and animate the canvas to change the menus
