10-sec pause mania (Ludum Dare version)

You are here to push crystals on specific spots for future plans, but there is a Eldrich horror 10 second timer watching every moves you make and cause chaos to the crystals ! Can you counter it ?

The first Ludum Dare game I made. Now I know that days where I have school is the worst days for a game jam game. It was 23 hours (11 pm) when I published the game.
