Thank you! Yeah, a lot of feedback mentioning camera movement problem and grabbing cubes, i will surely check on this problems in the future works.
About Splitter mechanic
You know, when i'm started making levels there was just a change color of a force fields mechanic. And previosly i never made a puzzle game before, so i started to notice that such a small number of mechanics transforms game into "Find a very obvious course of actions". So i added new ones, and there was no such problem for me after that.
About mesh colliders:
Yeah, I understand that primitive shapes are easier to calculate on a computer and I totally agree that it's better to place primitive colliders. But if only Unity had an easier way to arrange colliders. They have to be moved for a long time and each is a component of the object. Perhaps there are some tools for this that make this process easier.
