speaking for all slow computer/laptop owners..
stop abusing hittest ! gah !
ok now for the review..
the good :
a decent remake of a good game. kept my attention for a while.
angled blocks and pads are always nice to have.
power ups were well implemented.
visuals were pleasing.
the bad :
lags like a mother f#$%er (at least on my machine) my guess is your collision detection is highly inefficient. there are solutions for that and publishing your game as is shows to me that it was either rushed or you just didn't care.
strong bricks are a matter of taste. I dislike them. you used them a lot. so..
easy + strong bricks(i.e. not much brick smashing action) = gets boring rather fast. especially considering the many other versions of this game.
all in all a decent remake. can be much improved.
