A short yet enticing experience! I did read below that the character is made in Vroid studio, but it's still a very well designed one, super cute gal.
The tentacle monster idea might seem cliche to some but I say it's cliche for a reason, it's darn enticing! I love that kind of thing and I'm quite happy to see it featured in a submission. I like that you slowly unlock the different tentacles instead of just having them all right away, but I also appreciate the sandbox mode to play with after the main little story mode. Nothing much critical to say, other than I wish there were some sounds from the girl.
Over all a great little game, I enjoyed it quite a bit ^^
