Hard not to be tempted to give it straight 10s.
Random: Title, Preloader, Ending, etc...
So let's begin. I like the title Dad 'n Me, although I'd probably say Dad & Me would just look better, but ok well, at least you were consistant with the 'n theme when you had the preloader go "Loadin'". Also, I think it'd be better if ads and links were at the end of the flash rather than at the beginning at the loading screen. It's just took distracting and out of place at that point. The ending and preloading screens were fine and looked nicely done, enjoyed the font. Also, I loved the little intro video to the actual game. :D
Graphics:
I like the kiddish effect, but it still wasn't smooth at points, and was thus unappealing at times. I'd prefer it looking more crisp. :)
Animation:
The flash flowed very well. Even though it was a game it didn't have animation defects and that is good flash usage right there. ;)
Style:
Well it's original for the most part, except for the whole thing of it reminding me a lot of AH. After all, sidescrolling, plenty of random killing, etc... D:
Sound:
As always, a good choice in using Dustball's audio, he's just so good when it comes to audio. The sound effects were ok for the most part, a bit distracting at points. :D
Violence:
This could have been improved through not just having the enemies disapper. Instead, a dead body in a pool of blood would have added to the gore needed in the violence department. >:D
Interactivity:
Good use of the keyboard arrow keys, but you didn't take full advantage of the aswd keys and limited yourselves to a and s. o_O
Humor:
The whole concept of this was pretty funny, especially the intro and death scene when your HP hits 0. :o
Overall:
I can't wait for this game to hit the shelves as well as more of your future works/games. You've improved a lot over the years (both Dan and Tom). ^_^
