Good job! I've always liked the "atomix" line of games. The only drawback of the game is the 30 levels, which seem a bit sparse compared to other remakes. For example, the very old Watomic, despite being very basic in graphics, has 85 levels.

And we puzzle fans love levels! This brings me to a question: are those 30 levels original or are they modified versions of already existing levels?

That 30 levels are exact replicas of the original ones. There was 1 bug fixed (somewhere around level 22) which prevented the level from completing which is the only difference.
