I dont really 'get' it... just seems like a lot of sitting about and not really a lot going on to hold interest. Maybe it will appeal to others more but thats my opinion.
Get rid of the labeling EVERY piece in EVERY level... Only at level 8 and Im sick of it already.
Introduce a new piece and label it so people can see what that piece does. Then leave. People are quite capable of remembering without having bloody flashing lettering on everypiece bar the normal nodes.
Time attack doesnt really work... it says go for as long as you can whilst the laser gets higher but the balls run out eventually... Its just the normal mode with the laser getting higher not time attack.
Wasnt difficult at all.. everyone know to check things like words and the hieghts of things in these types of games... and all the differences were simple things done with a photo editor. That being said it was well done and the black and white was different.
Also for people that say they have trouble seeing things in these types of games... a small tip... Ctrl + will make the zoom in the screen and Crtl - to go back.
