Hi there, I'd like to start this off by saying that I thought the game was great. The environments are beautiful and there's a definite attention to detail here. One area that really stood out to me is the room with the model planets, the lighting and reflections are absolutely amazing, it practically melted my eyeballs. I also found the use of alternate character forms to solve puzzles and explore the fantastic environments to be one of the strongest points in the game.
I only have two complaints with the game, one is in regards to how it controls. Most of the time it's fine, but there are some occasions where it's really difficult to get onto a box or other object no matter how hard you try. I imagine that this might alleviated with the use of a controller , but I digress. The other complaint is with the story, I did read the full synopsis here on itch.io and in your provided press kit after I completed the game, it certainly pieced things together but I think some sort of indication on what's happening within the game would be great.
All in all this is a beautiful little adventure with some fantastic looking environments. I love that the game gives the player new abilities but doesn't overload you at the same time, and each ability has some practical use even in the later areas of the game. The controls complaint I have is more of a minor annoyance than anything of substance. Some indication of what's happening story wise would be lovely, whether it's through the use of a narrator or perhaps just a few short written notes.
I definitely enjoyed my time with your game. I hope you don't mind but I recorded a let's play of it for my channel.
Cheers and best wishes!
