I actually enjoyed the music during gameplay. It creates a feeling of chaos and frenzy instead of spookyness, which I found totally appropriate.
My main criticism would be balancing. You'repacing player actions by both cooldown AND resources. But I was almost always waiting for the cooldown, which felt frustrating. I'd much rather be blocked by a lack of resources (blaming myself) than by an artificial, forced mechanic (blaming the dev).
I'll also chime in saying that there was too much to read in the beginning. Especially with simple jam games (but also more generally I guess), people want to jump right in and not read lots of text before getting to play. What a lengthy tutorial leads to is that a player needs to invest more (time) before he gets a first return (fun). For casual games, you want to keep the player's investment outlay as small and short as possible.
