This is quite an interesting puzzle.
I like the main mechanic conceptually but I donāt like how easy it is to mess up if you want to just move away. Some sort of a conformation mechanic on pull to prevent that would be nice. Also, I spend a lot of time on Level 6 because I didnāt understand what do you mean by āmouldā. The fact that you need to pull one slime block against the other, and not push, could be explained better.
Graphics are nice and functional, and sound add a lot of feedback. Overall, itās a great entry.
