Very addictive...
This was well done. I am not usually the type to play puzzle games, but this was great. It was well thought out and very well executed. The blocks reminded me of newgrounds level icons. It had great effects and a nice background.
I like the way you even tied your preloader into your full flash. having the fish starring at you while you are trying to play can make you want to go faster. It looks as though you put a lot of time and thought into your flash. Great work.
The fact that there was such a variety of levels was very nice to see. This can certainly be a game to keep people's attention for a good deal of time. Most puzzle games loose players early on due to a lack of variety.
It would be good to see more like this from you. This was really good. It is nice to see people here on newgrounds concerned with the overall quality of their work. Things like this will sure help out around here. Keep it up.
