This is amazing! Love the simplicity of the concept of looping in a hamster wheel [but make it space]!
It looks gorgeous, the movement has great weight to it and it is quite satisfying to squish everything. :P
And if I am not mistaken, always having at least one hatch open makes you consider your movement to not get snatched.
High end nitpick if ya'll continue to work on it would be to visually highlight the open hatches in some way. Because like many I glossed over the [cutely animated!] gameplay-descriptions and it took me a few deaths to figure it out.
Great job! [Also on uploading early! ;) ]
