Very Nice coloring in BLAST. A couple of comments 1) can you make the S pointed on both ends and maybe have the A facing more forward instead of facing left. 2) #18's confetti is really good with definition similar to your letters in Blast. I like the conffetti in #18 a lot. 3) I am not liking the presentation of Arcade - Laser Maze and It's all fun and games. #12 and #13 is a bit more of what I like with the bottom wording.
Here is a thought. Try putting Laser Maze - Arcade instead of Arcade - Laser Maze. It may fit better if you make the S a bit smaller and split the words on each side. "It's all fun and games!" should probably be at the bottom.
#23 is brilliant! Try changing the font on "It's all fun and games!" (with an exclamation point) to a print font (not cursive). Believe it or not, but in the U.S. schools have begun to not teach cursive writing and some children can't read it. So, I think a nice print font might work best.
The dark backgrounds are really nice. I would like to see them with the S in Blast with both sides of the S pointed. Also, try switching it back to Arcade-Laser Maze. You will probably have to make the S a bit smaller, but that is OK.
Great job. I like the style of 30, 34, 35. Only 3 comments this time. 1) Please center the dot between Arcand and Laser Maze, and add a dot behind Laser Maze. 2) I prefer the lighter red background as in 25. 3) Please cover the little piece of the A in Blast down in the very lower right corner of the A.
