I loved it!
The story is very nice and well told. What surprised me the most were the sound effects, superb! Usually this is a neglected part of jam games, but you nailed it!
Just one think I'd change: you walk with AD, follow dialogue with Enter, but have to select the lines with the mouse. There are basically 3 places to use my hand in the keyboard/mouse. I'd personally prefer just 2 places, for example select the lines with WS and confirm with Enter would be a possibility ;)
Congrats again, great entry!
