Game Over - I really like the beat of this song, though it is a kind of repetitive, but for what it is its pretty nice.
Winter Break - This song is really nice, its got both chill and happy vibes, I like that a lot.
Graveyard Battle - Feels really spooky, its really fun to listen to. Probably less fitting for background music but its also my favorite!
You managed to fit your songs to the theme really well and overall I think you did a nice job. Keep up the good work!🔥
