Update v1.2.0 is released!

I adjusted difficulty.
I made easier ‘Normal’ mode. Attack of enemies turned soft, and sound sensor is shown always.

Concretely, on previous ‘Normal’ mode, enemies approach quickly toward a player while the player is taking actions: running, recharging his flashlight, and dragging a block. It seemed that an enemy teleported for a player who don't know this system. On current ‘Normal’ mode, this system is abolished and moved to ‘Hard’ mode. Run away from enemies to your heart’s content even if you are in front of them, on ‘Normal’ mode.

About sound sensor. Sound sensor is lines surrounding player. I made it shown always. Previously, sound sensor is shown only when the player stops. It was raising difficulty.

This table shows the difference between v1.2.0 and previous version.
