Ok, so these are some of my thoughts during this level
In the beginning: "Oh, a generic section where you must blow up some bricks"
I got stuck in this section, and by that I mean I couldn't get out to get another bomb, so I had to place a block to get out.
After that: "Ok, a pipe... OH, GOOD! ANOTHER GENERIC BOMB SECTION, EXCEPT THIS ONES HARDER THAN THE LAST!!!" You have to blow up a wall, which isn't fun. Don't do this
After that: "A section with 3 koopas... why is this even here?" This section is completely useless.
The last part (I'm serious, the last part) "Ok, a section where you use a koopa to break some bricks, cool... I guess."
And then the koopa walks off screen, sending you into a freak out, because you couldn't beat the level, but then
"Oh, he came back... WHY CAN HE EVEN WALK OFF SCREEN!?"
You then use the koopa to break the bricks, and you get a fire flower "Ok, cool"
You then enter a pipe, and the level ends... WHY!? Why do you give the player a fire flower, but then have the level end!?
The only thing I like about this level is the use of the underground blocks, which are pretty good, I guess.
Overall, this isn't a puzzle level, its not fun either. I give it a 1/10.
