For starters i liked the ambient music! it gave me a calm feeling. Telling me that there is no rush to do anything.
I did though think that to capture these creatures was a bit tedious, or not tedious but maybe too many steps before you get them.
I liked the sound memorization part and the press directions in the correct order part! But maybe use them separately as their own parts beofre capturing the creature? and not to combine all of them in one capture..maybe use the directional things for one type of creature and the sound part another or something. And also the sound effects are tad too loud! :)
Other than that i liked the depth, athmosphere and the exploration in general. And nice graphics too! :) really cool! A relaxing game!
