During moderation the author fixed a bug where the Platform blocks would crash the game when jumped on, if all the sprite slots were already full. Everything else works as intended, so, accepted. Also, during moderation I tweaked the sample level's palette, since it included unnecessary colours, and added a pal/palmask, since one wasn't included.
Aside from the poof effect, how are these different from Akaginite's?
The first one is that you can place the platforms standalone and not just as a block (hence why I submitted them as sprites and not blocks) and the second reason is more compressed Map16 which allows you to use platforms with larger numbers than Akaginite's platforms.
You shouldn't always assume that the submitter is uninformed. I have got a very good reason why I created my own version: I'm not happy with the existing solution (the reason is even mentioned in the readme). To give you one defining example why my version is surperior: Blocks. smkdan's version is strictly sprite only, mine not only allows you to place them standalone (i.e. as sprites) but allows you to place blocks instead and those have got multiple advantages (see the readme for more details).
