Ok, it's similar to space is key, you're a square and you gotta get from side of the screen while avoiding obstacles using tap to jump. Here though the screen is divided into zones, you complete zone one travelling from right left, zone two from left to right and zone three from right to left, with no pausing inbetween so you have to kind if look ahead to the track below as it's very easy to smack straight into the first obstacle. Bits of text pop up to give clues or take the piss by asking if you give up. I've got to area fiveand the cube you control disappears making a difficult even more difficult. Wonder what other scanners the dev has thrown in for later areas. It's the kind of difficult that makes you determined to beat it though.
It would seem you have to complete it all in one go as if you pause and leave the device to sleep, or close and reopen the app,you start right back at the beginning, there's no continue button or level select, which is frustrating as when you pause on a low death count and then struggle on the next run. The lower the death count the better. There's no indicater as to how many more areas are to come so I can't say how long a play through will last so make sure you empty your bladder before playing. (That's why I had to pause lol)
Other than no continue button I'm having fun, it's a fun twist on space is key style. Worth a look if you like that type of thing.
