Better than your 1st, but I have suggestions =)
Before I start I wanted to say that it's cool that you take comments people leave and turn them into a reality. I remember from your first game how the instructions were kind of hidden and now they are right out there in the open =)
Anywho, on to the review of this game.
I'll start with the things I liked about it:
* I liked the start up menu. It was cheesy looking but I like cheesy things. For the future you may want to have the boxes that pop up when you mouse over someting grow to full size a bit faster. Not dramatically so but just a tad bit.
* I also liked the music. However, I do agree that it shouldn't start until I press start.
* The witches screechy voice was also quite amusing (along with the drawing of her face)
* I thought it was an interesting idea to have some lag incorporated in so that it's not just another move mouse around in a circle game. It made it a bit more tricky, but added to the game play (It did, however, kind of get annoying at the different speed that it would go. I sometimes wanted it to go one and based on how fast I moved the mouse it changed).
* The black vortex thing to end each level looked nice.
However, as before, I do have a few suggestions for you to improve in future games.
* First off I really disliked the depiction of the broom in the game. It took me a bit to realize what it was. I'd improve the character drawings inside the game (your ones outside of the actual gameplay were good - like the witch)
* Secondly, the collision code caused some issues. Based on how fast I moved my mouse around it seemed to change where I could hit each obstacle. It also made me jump around like crazy at times when I tried going fast. I would hit a wall and suddenly teleport across the map.
* Third, the levels were relatively plain. I'd suggest making them more unique. More features or enemies might be nice at times. It just felt repetitive after awhile. Power-ups or whatnot could definitely make it more fun. Maybe have like super broom where you can teleport once or have tougher broom armor!
All in all, it was a decent game. There's room for improvements, but it still kept me amused for a bit. Nice second game and I look forward to seeing what you produce next =)
