Hi! I played this on stream: https://www.twitch.tv/videos/1834468660?t=00h01m47s
The puzzles were fun, and I liked the last 2 where there was a time limit for one of them, and a jump mechanic for the other. They added a different pace to the puzzles that made it exciting, compared to the earlier tutorial ones where I could take my time, at a slow pace if I wanted to.
One suggestion is to split the tutorial into missions. Instead of one long tutorial teaching everything, maybe have a bunch of "easier" missions that slowly introduce the new mechanics. The story could potentially be largely the same, maybe with some small tweaks, so it doesn't feel like a long tutorial. I think the order and pace of the puzzles are good.. it's more of massaging the story so it keeps moving forward through missions, so that the player feels more accomplished rather than "finishing the tutorial" :)
I liked the little animations the characters have when they're standing, like they're breathing, blinking etc. I think the characters look nice overall, except the Ucogi's breasts seem... disproportionate.. the other woman looks more proportionate :)
