Hey man glad you liked it
The footsteps are the default footsteps sounds from unity, the pickup sound I had from an asset package that I still havent been able to retrace (I seriously need to refine the credits when I make episode 2).
As for the screen UI size issue I'm still learning how to scale UI properly in general, for this jam it just fit the theme to not bother with it, but thanks for the heads up!
Also there are 3 places I found where you can fall through the world counting the shotgun building. And another fun fact, if you pickup/switch weapons on a certain frame, it can actually be impossible to fire that weapon you switched from.
