Could do with more levels and maybe a create mode!? Also you should be able to tell which blocks will disappear and which won't, really good game though! Also level 12 was a bit too hit and miss.
There's a problem with one of the missions, for the one where you have to beat your maximum speed, I've done this a few times but I'm not getting the achievement.
