Very nice game! The movement mechanics felt very smooth. Took me just a few seconds to get the feel for it, and then I was flying around nicely!
I think it would have been nice to see the grocery list before the count down begins, to fully help emphasize what I was supposed to be getting. I was just picking up all the items, and wasn't really sure what triggered the last stand mode.
Other than that though, very nice game! Well done!
