Excellent game. I love a good tile movement puzzle game. Well done.
I did have a bug when using WASD to move it would sometimes move the coffin or block twice, which was frustrating, so I had to switch to the arrow keys, which meant using the arrow keys and the mouse felt a little weird. But that's an easy fix. I think adding some more SFX would help with the immersion, but the music was great!
Otherwise, solid game. Loved it. Maybe my favourite in the jam so far.
