The movement in a Gorilla Tag fan game can feel different from the original due to several factors, including variations in physics calculations, friction settings, and collision detection. Gorilla Tag's movement is finely tuned to allow for smooth wall-climbing, controlled launches, and precise hand interactions with surfaces. Fan games may struggle to replicate this due to differences in game engines, incorrect friction or bounce values, and inconsistencies in how momentum is preserved. Additionally, the way hitboxes interact with the environment can change how a player sticks to or slides off surfaces. If the movement lacks the same level of fluidity or responsiveness, it can make the gameplay feel either too slow, too slippery, or outright unplayable compared to the original.
