If you go inside you can see them and test them. I looked for scratch block ideas and using custom blocks made some of them. I know most of them are just a few blocks of code it was very easy to make. So far all block ideas come from @WindowsMeRules2000's project 100 scratch block ideas. I know I only made 7 but its very limiting without being able to make all the shapes. I will try to make more and hope you enjoy. If you want to use any of the custom blocks remix it and use the one/ones you want. Backpacking it also works. You don't have to give credit but do need to put a link to your project in the comments. No advertising random thing though just things using the blocks.
All ideas came from @WindowsMeRules2000 All coding came from @FairyBC also known as me (except pause/resume sound which came from @xXRedTheCoderXx
