I'd like to test them, but I don't know where to search

Unfortunately, I think that Morphic is only compatible with Squeak, but I may be wrong. After all, I never used it before. Leave it to the professionals to answer this question.

Ok, I thought it was for Scratch. I don't want to get into Squeak.
But, thankyou anyway!!!
