Don't understand whatever language that is in the feedback forms so let me just type it here.
Game is too short. Expected too much from the detailed description. Atmosphere building not enough for a horror game. Screen too dark to figure out what's going on.
The monster has a bit of cool animation though.
Can't walk after dying once.
Password system not cool. No backspace key. And it's just brute forcing, which is downright bad.
Ending screen is just badly made in comparison to the gameplay. Looks like a game that was published in a rush.
Anyway keep up the effort :D
