Haunted media is an enthralling concept to explore and I enjoyed your take on it.
The music stood out to me. It was spooky, a little chill and catchy. Was really digging it.
Love the CRT effects over the pixel art. Very retro/nostalgic.
The gameplay itself had a nice variety of parts. Starting with the cute narrative between the ghost and the haunted media expert using dialogue onscreen. I thought adjusting the antennas was a fun interactive way to start the game and introduce the player to the hardware they'll be working with as well as a nice way to ease into the main gameplay.
For the main gameplay you're basically controlling The Grudge on a SNES and I'm all for it. Great pixel art. The volume mechanic is creative and easy to understand. I felt like there was more than enough content for a game jam, and enough there to chew on the concept. I also really liked how you ended the game, but I don't wanna spoil it for anyone.
Very impressed. Nice to see game jam games with a lot of polish and yours even has controller support! I'm curious to see if you'll have any updates for this one.
