This a fun, fantastic, addictive game at a great price. Absolutely enjoying it. Developer is very honest. As someone else mentioned in their review, an editor would be nice to have so users can make additional levels. Highly recommended. I'm sure I will buy more of his games. Love that you can try out these games on Kongregate.com before you purchase here.

super simplistic, minimal idea executed amazingly. It's a very "enter the zone" kind of game, where you must get the timing down and stay r-e-l-a-x-e-d. A very nice way to pass some time and clear your mind.

Insanely difficult minimalistic arcade game that will have you pulling your hair out. The premise is simple really, flip which side of a circle you're rotating on, and progress further by going into new circles when there's an overlap, whilst dodging spikes, the main obstacle. The game only requires one button to play, but even then, it's ever so frustrating. Funnily enough, there's only four levels, which really goes to show just how brutal this game is, there's no holding your hand in this one, it's just straight into the hellzone. Apart from the four levels, there's an endless mode, which, as the name suggests goes on infinitely, as a test of your consistency. It really pushes your reflexes to the max as it keeps getting progressively faster the higher score you get, and in this mode, you can't take your time either, as a massive red wave is slowly trailing behind you, waiting to end your run. The four levels and the endless mode also have an alternative version. Basically, the visuals change to what it would be like to be high off of shrooms. This makes it all the more difficult to perceive what's going on, but it makes for a great challenge. Now, endless mode is cool and all, but there's a caveat to it. An achievement that requires you to reach at least 100 score in endless mode, the bane of my existence. If you're like me and your reflexes can fluctuate, getting to 100 feels like being trapped in an eternal prison, and when you continuously keep attempting it, your eyes start to lose focus and that slows things down EVEN more. But hey, when you are able to complete the challenge, you feel like a living legend, so I guess, it's rewarding in a way. A great title to test your reflexes, 100% worth it, especially with its cheap price.

Cool game, the main levels aren't too long so they're a decent size to be able to memorise (and there's breathing room to remember if required). The endless mode is really fun I like how the sounds and music get faster and higher-pitched as you go as well as spinning faster, it adds an extra intensity. I'll note though if you get motion sick it may be a bit much and there are achievements for the endless mode (it's the 2nd vid on the store page as of time of writing to see how much it spins). Wobbly mode is funny and knowing levels/patterns is even more key to that, but I haven't played much of that yet as of writing this review. The game is very cheap so I would say it's worth it.
