graphical glitches

[Party Parrot]

I've been really enjoying this game for what it is and got to the ice lazer teeth thingy titan. I noticed that he didn't have any teeth and I just saw a red box that didn't move with his mouth when he went down. then I noticed the snow that had a big box around every flake.

if someone knows what is happening to the game or what I can do to fix it please let me know
