So guys, just in case you didn't know. Platform Racing 3 came out, and I must say, the level editor is incredible! So, anyways... here's the link http://www.sparkworkz.com/platformracing3/ You should definitely give it a try.
COIN DOORS: Coin doors should include a blue coin door. COIN DOORS: Coin doors should include a door that APPEARS once a certain number of coins are collected.
What about a minor crown? I know it's not the BEST idea, but what if, to the winner of something, you wanted to award a crown, but not the one EE uses now. It would be kind of like awarding blue coins instead of gold. In fact, why not make a crown that doesnt go away when someone else touches the crown block? (Like the diamond block, but gives you a crown rather than changes your smiley)
How about a magnet block that pulls players towards it. Kind of like gravity blocks, but no matter where you are, 'down' would be towards the magnet. [+] if you agree!!
The reason I want blue coin doors is because if you want to put gold coins on your level (maybe a boss?) you can have blue coin doors as instead of gold ones when the players get a coin.
