Voez is a rhythm game, and works much like what Pop'n Music would if it was on a touch screen. I played the game on the Nintendo Switch and got around 100 songs for the price of $25, which is an incredible value. I have heard however, that on the other platforms the song packs have to be purchased piecemeal, which may be a much worse value. It is worth noting most of the songs are music only, and very few have voice tracks. The songs which do have voice tracks are mostly in Japanese, with a few in Mandarin. Most of the music is pretty good, if not quite all that memorable, with some stand out tracks and a few stinkers.
Voez is a hard game, and the difficulty ramps up pretty early on. The game has three difficulties: easy, hard, and special-- with special being the most difficult. I would expect most of the players would be able to complete all of the songs on Easy and around half of the songs on Hard; however, any songs beyond 10* difficulty even I struggled completing with a satisfactory grade. This highlights the game's biggest flaw-- it's grading system. The way it grades the player at the end of a song is based on the longest note combo they were able to maintain. No matter how well you perform in the song overall, you will be given a poor score if you cannot maintain long streaks of successful button presses. The game incentivizes further play through unlocking of diary entries which have certain requirements, such as completing 5 songs on Special with a B difficulty or higher. I suspect that the reward for completing very difficult songs is not worth it for most players, and due to the game's high difficulty, most will probably never see past Chapter 1 in the diary.
Voez is the first and as of this writing, the only Nintendo Switch game to require the usage of a touchscreen. Buttons do absolutely nothing in the game, even on the menus. Because of this, the game cannot be played in docked mode. I had no problems using the touch screen during gameplay; however, occasionally the menus would become unresponsive, requiring me to go to the Switch home menu and close and restart the application. Because of the large usage of multi-touch, both hands are required which makes it difficult to play this game on the go. Generally, one would be better off playing it on a flat surface like a table, or on your lap.
I enjoyed my time with Voez, and it was a fun distraction for a while; however, the difficulty and unfair grading system eventually made it tough for me to continue playing. I would recommend this game for people who are fans of rhythm games, but find it hard to recommend it to those who do not know what they are getting into ahead of time.
