TRY THE BETTER VERSION HERE: https://scratch.mit.edu/projects/460348550/ Z to select, X to go back, arrow keys to move the soul around. Tip: If you want to use ITEM, to make it more worth it, wait for the KR to finish. This is easier than Phase 1, but Sans has 2 ATK instead of just 1. Try phase 1 first. The song is pretty laggy.
