Enjoyed the aesthetics! The little fireflies gave this a chill vibe. This is the only project I've seen so far that has both a custom cursor and a fully voiced narrator! Very cool!
Unfortunately, the shell selection seemed to be finicky; I would mouse over shells but they would only get highlighted some of the time. I would have appreciated a planning mode where the game is paused and I could scroll through the cave and click on the shells instead of trying to do it while the timer is counting down.
All those poor dead turtles...
