Absolutely stunning visuals. Gameplay is a little shaky but the uniqueness and difficulty of the game completely make up for it. A great sequel to Boost 2. I look forward to more games by Lewis in the future.

Great Game, Great Developer, Needs Work

I love boost 2 and have spent a lot of idle time playing it, when Kayos caught my eye I was naturally excited to see that it was made by the same developer. The game looks to be in similar taste to boost, however unfortunately I can't give it a good rating until I see some improvements on the tilt controls. Boost's tilt controls were really well done and are one of the main reasons I love the game so much. Kayos' controls on the other hand are wayy to sensitive, even with the sensitivity bottomed out. As is it almost feels like I'm playing a reincarnation of flappy bird. I will be leaving this review at 3 stars until I see an option to further decrease the sensitivity of the controls.


Super cool and engaging

I like games where you must go very fast evading obstacles, so I sure played Boost 2 before. But Kayos is the most challenging and with those silky smooth graphics it becomes my favorite!
