Edit: made this a while ago but I have to prove I know scratch so I'm resharing it :) Update: Hi! This is the next version of Blocker! Not too many changes, but I have added one level, and Blocker now has five costumes. Press key 1 and you will get Blocker. 2, and you will get a cat. 3 for a terribly drawn dog, 4 for a dragon (my personal favorite), and five for an inverted blocker! Instructions: press space to interact with things, r to restart the level, arrow keys to move, and press m to see the menu. In the menu, you can switch between invisible ground and visible ground. Enjoy, - Viperstryke
I used this tutorial by griffpatch_tutor (Thank you) https://scratch.mit.edu/projects/67727504/#player It is very good and I highly recommend it if you are attempting platformers.
