Thanks for your compliments about the art and mechanics! We considered making it so the player would only pull a single slime block in front of them rather then the whole blob, but in the end we decided on the latter since we though it had more depth for puzzle design and was a better fit for the theme (scaling the whole object rather than a section of it). However, you are right in the fact that this unfortunately led to a sharp difficulty curve, where players sometimes get confused after a few levels. If we fleshed this game out with more levels I think that the main mechanic could be slowly introduced in a more intuitive way. Thanks again for your review!
