A good starting point

It was alright, it's kind of hard to judge these kinds of animations when everything moves quick and it's so short.
What I will say though is that this is a good starting place for you, what to improve? Maybe add some kind of actual plot, the sounds were fine, but maybe add detail and flexibility to the characters, even if you do keep using stickmen.

Um... what?

I don't really understand the plot, partially it might have to do with the text cutting away suddenly once or twice but also I think it wasn't fully explained.
The art was pretty good, but you didn't really do any animation except a couple of tweens and mouth movement.
About mouth movement, don't just use a couple of set images and usually if you're going to do it you'll include audio dialogue as opposed to text.

I really like this, please add to it

I like this a lot, but if you added difficulties (where the bar moves faster and stuff) and maybe some other minigames it could be getting a ten.

Useful Tutorial

You give some very good tips and it's all laid out very well, but you didn't have a section on fully tweening animations (which believe me, can be done well).
Also, I wasn't convinced by your lip syncing method, and it was a fairly brief nad vague explanation. As far as I'm concerned to do it accurately you need to actually look at your mouth in the mirror as you say the line.
But, overall it's a good, useful tutorial

Meh, it's alright

You might have wanted to test the game a bit more though, as it is it's a little clunky but more importantly, the chat window completely blocks the other player on the screen, that kinda ruins it. Also, even multiplayer pong is a bit basic, maybe add a bit to it or try a different game.

Fantastic Game, Perfect 10

This is brilliant, I love the system and all the different characters.
I have no criticisms at all for this game, and that's saying something.
