As others have said, the atmosphere here is cute. My first question however, is why did you use white text on a faded white dialogue box on the intro? It made it a little hard to see! I also wish it was skippable (for repeat plays) and there were a few typos - not a big deal, but something you should be aware of.
I love the short minigame type of gameplay. I did find that by the time I'd read the instructions for what I was supposed to do, my timer was already halfway depleted and sometimes I wasn't getting the interaction from the objects I was expecting: the toothbrush sometimes wouldn't move. My crab also wasn't moving with my mouse to avoid the objects. It felt very stop - start and left me wondering a little.
I understand it's quick shot gameplay but if it isn't so intuitive as to be instantly understandble, I feel there should be a popup panel that explains prior to kicking off the timer. Some of the instructions also left the edges of the screen (I am playing in the browser, not fullscreen).
I absoloutely adore the layout of the hub world and the artwork of the entire game is extremely appealing. I see what was being done here and I like it very much, I just feel that there is a little clarity missing in it's execution. Regardless, you should be proud of the entry.
Congratulations on your entry!
