First, I must say that this is a very clever idea to merge Scratch with Tinkercad this way - very nicely done. I started in on designing things and immediately ran into serious limitations though:
There needs to be copy/paste or duplicate capability for code - otherwise it's really tedious to do anything complex!
I like that you can create and reuse an object, but don't see any way to pass parameters to one. Please add a way to do that!! Otherwise objects are a lot less useful than they could be.
"Count with" loop variables - if you use the same variable name in two successive loops, it behaves wrong - it appears that the variable is not reinitialized correctly the second time around.
How about an "if" statement?
Thanks for considering
