Deception is not a clickteam game, It's a full game made in Unreal engine with a lot of content including even cutscenes as an mp4 files to avoid potato PC explode . The game is not short game too, for first time players it will take at least 5 hours to beat it without collectables and only with one ending. There are also some usused content in the files that affects the game packaging and for some reason cannot be packaged without these files.

also gonna say that most of 3D games (Esspesially made in Unreal engine) requires more space than Clickteam/GameMaker games that most of fnaf games are made in.
