Well.

Great idea and some pretty interesting levels
however, you should have definitely polished it some more before uploading it
some of the graphics just seem really unfinished. Take a look at some of the more professional flash game designers out there - such as http://orisinal.com, or the games on http://jayisgames.com . You'll get a better idea of some different styles.
overall, not bad.

Well.

It's not bad
the graphics seem a bit rough - stretched Mochis dont work too well for me.
It's really random in a sense that there's no sort of style. you've got a high quality jpeg as the background but some really low quality characters - and a really awkward score bar kinda thing at the bottom. The game could be more logical in that there's a reason for using Mochis and/or bombs - perhaps the mochis are catching coins or avoiding flash files, or something like that... It would also be nice if there were levels/ increasing difficulty :) (and if there already are that i didn't notice - ignore that comment.)
Otherwise, great concept. Well done. Just needs polishing.

Simply Cool

Well done on taking my game to a whole new level! Loved the powerups and your style worked great with the game. However, i recommend you make the height of the game a bit smaller - for small screen-ed people like me. :)
