There's a lot of good stuff here. The graphics are big and colorful, the characters are adorable, the music is awesome. Even the sound effect are pleasing. I loved the little hollow "knock on the head." The game is fun to play, and it even gets somewhat challenging. There's enough time to screw up repeatedly and still get the best ending.
The cut scenes are pretty well done. The characters have some funny moments. I like the pause screen too. The ending I saw was funny.
What really bothered me, however, was the way the objects were randomized during a run. Toward the start of the game, everything you need comes regularly, and the challenge comes from timing the pick-up without swallowing something else, particularly when everything is group close together. But as the game goes on, needed items become less and less common during a run. I have this sense that it has something to do with increasing the difficulty, but think of this: as the game gets harder, the player goes through more and more stretches where he just sits there doing nothing while upwards of 25-30 items bounce by. It was annoying when I had to use an entire day to get 1 missed item simply because it refuses to appear on the previous day. Some items rarely appeared at all. I would think I'd finished a level, almost out of time, and then find out that I still had like 8 more of a specific item that was barely appearing at all. Just sitting there WAITING and WAITING and WAITING while I got increasingly worried that I was going to fail the day because I wasn't even getting a chance at scoring the item I needed really angered me.
Also, there were a few times the dog came running up from behind for no apparent reason, ending my day. It was usually very early, and I hadn't choked on anything, or maybe just one thing.
You might also want to add a mute button. As great as the music is, some people might want to listen to other things. Lastly, how about a button that will allow us to exit back to the title screen or the scrap book screen if we don't like the way a run is going?
