I like this game. it's short and fun.
The controls are a little fast for how precise some of the movement needs to be, but it's more then manageable. And some levels are more of a try and error then puzzle, but over all it was nice.
What I can say that I really like are the visuals and the audio. The visual, while simple, the are very cute. and the calming music does makes you feel like in a dream.
A full screen button would very nice (at least for the web version, this is the one I played), but that should be a quick fix from the project settings and it's not like it's unplayable without
