A Japanese cult-classic video game and it's not hard to see why.

A relatively simple but very memorable game with a lot of polish, Irisu Syndrome! really fires on all cylinders with addictive gameplay, an absolutely outstanding soundtrack filled with melancholy tunes you could spend a whole rainy day just listening to, and a genuinely intriguing story unbefitting for a puzzle game of this type that maximizes your immersion as the mystery unfolds by encouraging you to look outside of just the game window for more.

As a fan of many other types of colour-matching puzzle games, the dynamic style of gameplay in this is particularly refreshing, giving you very tight control over the descent and spin of the falling pieces and having a superb balance of risk and reward. Thus, although pattern recognition of the falling blocks is still an element, you get a euphoric sense of improving your finesse in moving pieces between tighter spaces and in more precise directions over time like an action game.

It was definitely worth getting all the endings and files for this and I will have to start a search for more puzzle games that scratch this same itch.
