sets up the story well and it's kinda cute
Though I kinda enjoyed the intro the first couple of times, it's kinda annoying now.
I reckon you should have submitted 3-1 and 3-2 in one submission. The size limit is 10MB, so it wouldn't have been too large!
I liked the mouse design and the part where the portal opened was rather cool. Also, I liked the start with the typing noises and cool design. All too often though, I kinda find the graphics and animation somewhat lacking with the tweened body parts not always matching up too well.
This half sets up the story well and it's kinda cute how 'simple' sherbert's personality is.
