Nice game, there is a lot of work for polishing but the ideas are here and it is a total fit to the theme. I must admit, the game does not feel super great for now with its control as everything I did looked clumsy to me but I finally matured :p
Now, the environment is really pretty, it feels like the most advanced part of the game and this is great. I didn't feel much sounds effects, the music is good but maybe too short, it feels a bit empty on that side to me. Maybe if you put a bit more sound effects when items are grabbed, when water is being absorbed... It could really add something important to your game for little work I think. (Also you should try to fix that space jump haha)
Anyway, I know it is about time so it's a pretty good job for the time allowed, congrats!
