Finally it's in the right place.
Review.
Fun: 4/10
Quite meh. While an intresting remake of Buoy base, the level lacks of challange at an extreme point and I should also tell you something: you can get in the pipe without using the bulet bills. Sorry

. Anyway, inside the pipe the challange was beyond pointless, really easy. Why not add some enemies? Some fire towers? I know maybe those weren't in the original, but when making a remake you should try to make it fun. The tower was as bad. Sure, you added some thwomps, but it needs a lot more than that. Again, add enemies, fire towers. The time challange was pointless as well. Why not adding more blocks? It's way too short and you have plenty of time. But what hit the level the most was the repetitiveness. It was the enitre same thing during the level.
Graphics: 2/5
Even though there was a variety of titles used, I don't think it was enough. Where's the background inside the underground challange? Why there's none? And also, why did you choose the Black background? Shouldn't you have used Space?
Other: 3-1.5+0,5=2/5
-0,5: The title.....really. You can't do that. You can claim that your level is awesome (do that in the description), but not in the title!
-0,25: Give you creadit for the bullet bills part for making me enter in the pipe, but it didn't work.
+0,5: No lag or loading time.
-0,5: No original ideas.
-0,25: The sign, while funny, lacks puntation.
Overall: 8/20 (2/5)
Em....not a really good level. Don't make me wrong, I can see you making a great remake of Buoy, but it needs more time and dedication. More graphical work and more gameplay variation. That's the way to go.
