This is a very simple mechanic of being able to pull and push blocks within the environment. This would later be used to solve puzzles.
The way this locking on mechanic works by using what we had before and adding a lock on target effect. Once you hit a magnetized object the magnetized rays point towards the point that they hit regardless of where the player goes. This gives sort of a grappling feel.
This grappling feel was definitely very fun and could work in our platform puzzle environment but the problem is that it starts go away from the realism of magnetization. Mechanics such as this could be fun in a platform puzzle but don't represent how magnets really work. So we have to ask ourselves if we were interested in the mechanics or the realism of magnets.
