Sweet Dreams

It is clear that this is your very first game. I think that the mechanics you do have are worked out quite well, and the music is great. But there also is a lot to improve.

I don't want you thinking that I'm being overly harsh, because I want to help you become a better developer.

First thing I noticed, is that the assets used all have a different art style or resolution. Unless there is a story reason for this, this is usually a little weird. Even if you use external assets, try finding ones with a similar style and resolution, otherwise it'll feel a little weird.

Secondly, the gameplay doesn't really scale. What I mean with that is that it doesn't really become more difficult as the game progresses, and nothing is added, which makes it a little boring. Even though the story is about the girl dreaming, in the game itself there is no sense of progression in the story, and there is no story reason to change to a different setting, so I would add some kind of story based reason to go from the first cloud level to the space level, so that it doesn't feel out of place. Also, the gems right now don't seem to have much usage.

If you want to add more depth into the game, you should consider looking up how to use a parallax effect in your background. This will make your game look a lot more alive and professional.

Lastly, some of the keyboard controls in the controls menu are incorrect.

Again, don't get discouraged by this! It's really cool that you are making a game in the first place, and I want to see you improve. If you are really interested in things like this then keep looking up things in tutorials and play other indie games, that way you'll be able to learn a lot.

The last thing I want to say is that the voice acting was quite good, and it did add some personality to the character.

Keep going and I'm sure you'll make great things!
