Thank you very much for your feedback !
I totally agree with you about the lack of landmarks. If I could change something, I would add more 3D props (different kind of trees, rocks, roads, maybe vehicles ? a lake ? buildings ?) and I would remake the level design from scratch. Maybe we could take inspiration from the game Slender to make clearly identifiable areas.
We tried to do out best on the sound design, but I feel like there's room for improvement too.
The "shriek" you heard came from some Watcher trees. They are not dangerous, but they call the Monster when they see you. When you hear the shriek, either the Monster is far away and you have time to flee before it reaches you, or the Monster is nearby and you need to close your eyes quickly. Also, the Monster is wandering in the forest and can still find you by chance, without even hearing the shriek.
Do Blink was made in a few days during a game jam.
At first, we did not plan to update it that much. But the game is still downloaded and played regularly by new people, so maybe it would be worth our time to keep updating it. (I can't promise anything, the original team split a while ago).
Anyway, thank you again for playing, and for taking the time to give us proper feedback :-)
