This is very awesome game, and good idea with the theme. I love the art and sound they are adorable! :D
I only struggled a bit with movement, it felt a bit abrupt but maybe it is due to me being used to other games movement style and needing to take a bit more to get used to this one. Which also brings up the matter about space bar button as mentioned in the comment below me.
I wanted to give feedback on the "bad" things because I think that is the most useful feedback anyone can get.
Either way great job for real! Good game :)
