It's nice that you added a playable tutorial, but there were still a few more problems. And that's not including the egg puns, there's too many of them.
I tried to play this yesterday, but the loading screen got stuck. I tried again today and it worked OK, but why was there explosions?
Next, I can't hear the sound effects, they're too faint and the music drowns them out. Maybe I can hear them better if the music can be turned off, but no. Also no WASD?
And why is there a blue key in the second level? I can't find any doors that accept it! There's a yellow door, but I can't find that key. It also didn't help that I didn't see the key.
The third level was very difficult to navigate. The music in this level doesn't help either. I actually agree with Stepford with this one. They made a good point. At least the blue key has a door and I can actually go there, but past that door, thank God I had stocked up on milk and had my health boosted, I kept getting attacked by rats and what looked like a set of walking udders. Not the most creative enemy designs.
The fourth level was a huge joke. Just go from left to right. At least that's a break from what is yet to come.
The final level is a boss fight. Is this the Farmer Figg that runs the place? Anyway, he's very difficult. Good thing milk fully restores health as well as adds a new hitpoint. I can't avoid taking damage here and kept dying a few times. That's where I gave up.
Here's some other points:
I like that there's a new music track for each level, besides the first two.
The game over screen looked worse than the rest of the graphics.

EDIT: I beat Figg, but you two couldn't be arsed to do a decent ending. What happens after you turn him into cheese? Also good luck beating him without any health boosts, if not without taking ANY damage.
