Vicarious Visions, the developer of the Crash Bandicoot N.Sane Trilogy, has confirmed that Crash's jump and the collision system are altered from the original games, meaning that some jumps 'require more precision'. . This comes after fans have been speculating, since the game’s extremely successful release, that the new trilogy feels different to play.
The editorial manager of Activision, Kevin Kelly, has broached the topic in a blog post. In the blog post, Kelly confirms the physics in the N. Sane Trilogy are indeed different, saying that the jump metrics are roughly the same as the originals, but that there are differences in Crash Bandicoot: 'Chief among these being the fact that you fall more quickly upon release of the X button than you did in the original first game.'
Kelly also says that the new Crash engine 'features a different collision system' which means that 'certain jumps require more precision'. Players have speculated that the difference in the collision is because of a change in the hitbox dimensions. There is no further clarification on this officially, but Kelly's confirmation that the system is indeed different means this speculation could be correct.
Crash Bandicoot N.Sane Trilogy’s jumping mechanics were originally based on those from Crash Bandicoot 3: Warped, but these changed, resulting in the developer fine-tuning them for each game. Kelly suggests that, of the three games in the remade trilogy, Crash Bandicoot is the most difficult, and new players might want to cut their teeth on 2 and 3 first.
