As a remake of one of the classic video games for the Sega Master System, Lizardcube did an excellent job of making a blast from the past.
The animations, the soundtrack and all the stuff in between are pleasing for both sight and hearing.
I must say, there are countless of times I enjoyed the soundtrack while I'm on my travels to places in the real world. There were times I want to do a little dance.

If I had to score this, 11 out of 10 for sure.
Great job and keep up the great work. :D

(Alex Kidd in Miracle World as a possible remake in the future, maybe? lol)
(Update edit: There is now a remake - Alex Kidd in Miracle World DX)
