This looks really great Tokinsom. Very good job of all the team so far.
A few questions to start, is this webGL or strictly canvas ? And what browser for the render ? I'm guessing chrome. Finally what screen recorder did you use to shoot the video ?
A few notices about the game. It is strictly from seeing the vid, the result in hand might give a different feeling.
The plant in between 3 platforms, requiring a "tornado jump" (around 1:43) took you three trials compared to the fluidness of the rest.
Is this peculiar place of the level too hard/badly adjusted to the keyboard controls ?
It sorts of break the flow of the vid there, arising interrogations.
The looping of the music is a bit abrupt (1:23 - 1:24), better smooth it a bit before the completion date <img src="smileys/smiley2.gif" border="0" align="middle" />.
Else, this looks like some platformer made by and for those who love platformers.
This also looks like a nice game to promote C2 once it is out.
Once again, good job, can't wait to see the final product.
