detail and realistic behavior of Trico and the boy were "emotive in a way that most developers wouldn't even attempt", potentially being the reason behind the long development, praising the effort put in by Fumito Ueda and the developers nonetheless. US Gamers Jermey Parish believed that Trico as an in-game character with its own apparent volition was revolutionary in character design, and that the emotional relationship between Trico and the boy was something that could only be effectively done with the interactivity of a video game. In contrast, Marty Sliva of IGN was critical of Trico's behavior during puzzles combined with camera controls making sections of the game more frustrating, particularly during interiors due to the cramped nature of certain levels and the size of Trico detracting from the experience, calling it "rare to even have to think about the camera in a third-person game in 2016, but I found myself constantly being pulled out of the experience trying to wrestle with my point of view". Sliva however still felt that the game succeeded in the attachment with its characters and delivered memorable moments despite its issues. Game Revolutions James Kozanitis found that there were moments that Trico would continue with traversing the environment and performing tasks even without player input, making the act of controlling Trico at times "ineffective and unnecessary". Reviewers also noted performance problems with the game running on default PlayStation 4 hardware. Eurogamers Digital Foundry determined that the game ran into rendering issues and framerate drops on the PlayStation 4, while running at 1080p on the newer PlayStation 4 Pro provided a stable framerate. Philip Kollar of Polygon compared technical aspects to its predecessors release on the PlayStation 2 due to the long development across multiple generations of Sony consoles, stating that the game at times did take advantage of the PlayStation 4 hardware while in others, such as framerate and control issues made its age more noticeable. Sam Byford of The Verge commented that while framerate drops were common in Shadow of the Colossus, they were more acceptable based on the PlayStation 2 hardware of the time and the extent the game maximized out the console's hardware, while such issues on PlayStation 4 for The Last Guardian were less forgivable, making it feel like "a PS3 game that never really came together until the brute force of new hardware allowed the team to ship"; he
