I actually really liked it. Was a beautiful experience playing it, the music in the background along with the cave design gave me a relaxing feeling... Also, is this game already finished? I got kinda far on my second try of trying to beat it but after some time I fell like in an abyss and couldn't get out since there weren't any bubbles.
Anyways, I really enjoyed this, even though I didn't get extremely far or/and completely understood the concept xD ;-;
