Has Minor Errors
-The placement of this one Thwomp is really annoying. I suggest removing it, because it's pretty hard to get the powerup (mainly if it's a mushroom).
-Maybe it's just my horrible playing skills, but I still find pretty hard to get this bomb without sliding to my death. Adding another block here would be nice.
-It was very annoying to get to this ledge without being hurt, mostly because of the metroid donut blasters here. Maybe adding more blocks would fix that.
-Now a more serious bug: If I try throwing the 'pipes' while running, I'll get pushed forward, almost always leading to my death. I didn't consider it a major error because I'm not sure if it's fixable, but I'm mentioning it anyway.
Otherwise this was a pretty neat level, it was very creative and challenging. It would be a awesome Mid-Late level, in my opinion. (Maybe a fortress/castle?)
