Lots of crappy puzzles and terrible solutions, sure some are creative and use lots of niche mechanics in roblox but that's the thing, it's niche mechanics that almost no one knows, now the concept of hidden mechanics would be good on paper but it was executed so poorly that I dropped the game after getting most of the badges. If you want some good and decent puzzles then I don't suggest you play this.
No real hate towards the game, just expressing how I feel about it.
