My levels aren't getting much playthroughs or Stars anymore so this update couldn't come any sooner. Hopefully it'll get some more player to play this again.
The keys and coins are a good addition. I could have used them in some of my levels, the thwomp pillar thing too... Too bad you can't update old levels (without reuploading), but at least I can get to use them in a new level I was working on. Just in time too, because at least the coins fit the idea.
