Thanks for the comment, was really happy with how the music turned out too.
The drop shadow is a good pint actually and something that didn't even occur to us at all to be something to add.
The blue platforms being jittery is an unfortunate side effect that after some post-jam research happens when you use the "easiest" method for moving platforms such as this one in Unreal Engine 4. Since it didn't affect the playability of the game too much I didn't dedicate time to fixing it.
