This was fun way to pass half an hour! Nice, cute graphics, an easy to pick up and use control system and interface and a nice little increase in difficulty going from level to level!
It did feel a little bit like the levels just started ticking along after a while, and if you ever make updates to the game I think adding extra ingredients as the level goes on and making the drinks more complex might mix things up a bit more =)
For what it is though, this is a great little puzzle / arcade / drink-mixing game that's well worth checking out if only for the adorableness of the slimy customers!
Keep up the awesome work Kendall!
