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.
