This looks like a good start for a bigger game if you feel like making it. It would need something more game-like though, such as a way to fail at the match-3 game or something unlocked by doing it enough. I'm not sure if there's an ending, since after a while of going through rooms and doing rounds the game crashed.
There's a couple things wrong that could use fixing if you have the time: 1. the instructions at the menu are fed to the player way too slowly. I can see that presentation potentially helping players who are younger or just generally not good with consuming information quickly, but for someone used to reading a lot, it just gets annoying. 2. the rotation and movement during the 3d sections shouldn't be linear. Having the character just move a set amount per button push gives an impression of extremely high acceleration that makes the game more likely to nauseate people who are sensitive to motion.
