OH MY GOD! those update are just perfect!

what an amazing game....... and keeps getting better.....

We need a direct soon!

Nice, really like these new additions!

I've been waiting for the part where you can have a power-up that is a mushroom when small, but something else when already powered up. Some of my levels became harder than I wanted them to be because of it. edit: not being in the game, I mean. 

Other than slopes, that's basically everything we could ask for an accessible creation tool.

The last two changes, Nintendo levels and event levels, are welcome, but I'd have preferred more extensive searching tools for typical courses. Give me the ability to sort courses by game engine, setting, upload date, etc. I don't want to be buried in self-playing levels any more than necessary.

Great! Cool additions. Maybe we can even look forward to even more added features in the future.

Now we can make long adventurous levels without worry! They weren't clear on if you can have multiple checkpoints though.

Those updates are awesome! :D

Great updates!
Especially the first two.

Wonderful! There are a couple of other things I'd like to see added but checkpoints and mushroom/flower blocks were the main items I felt like the game was missing.

Amazing news
