The game is quite simple, so this guide is fairly bare-bones as well. These are more or less just tips on where to get the achievements most easily, as there is really no easy way (except cheating) to get them all.

The game is largely based on skill, or rather sense of time and rhythm, though you can use a real clock (that shows seconds, one with just hours and minutes isn't going to help much obviously) to help. That might be a bit low, of course, and then the game would be about imitating a clock, instead of simulating one. There are really just two types of achievements, both heavily skill-based: playing well for a long enough time, and being precise enough to get 'perfect' taps.

First achievements we aim for are the ones for surviving a single mini-game for as long as possible. As perfect taps are the harder part, this should be gotten out of the way first. Get yourself used to being a clock by playing the various mini-games until you unlock the mini-game "Pig got the rhythm". This mini-game is easily the least forgiving in the long run and has a wide margin for error. If you miss once, it's game over, but the timing window is much easier than in the others, where small mistakes will cost you the whole run almost certainly before you reach the 5-minute mark for the last 'survival' achievement.

In addition to having the biggest timing window, there is also both a visual and aural cue, so you don't need to rely on your sense of time at all, really. So, I'd recommend just playing 'Pig got the rhythm' until you can last the five minutes.

TIP: Closing your eyes may actually help, as you have less to focus on and the audio is fairly easy to follow. Turning the volume up can also help.

You need to get 10 perfect clicks in row for the hardest achievement. This will be hard. If you have a very good sense of rhythm and time, you already got this from playing 'Pig got the rhythm' till you could last 5 minutes, or even before that, but most likely didn't. The game (at this point, at least) doesn't really tell whether you got a great or a perfect hit. Most modes don't even show the difference between a great and too slow/fast hits very clearly.

This is best done on a fairly forgiving mini-game, which has a good visual cue on whether or not you're doing great. Most just make the hand of the clock shorten slightly, but the mini-game 'A minute or perfection' clearly shows you whether you got it right or not: green means great or perfect, red means too slow/fast. Another one, slightly more forgiving (I think, at least), but with the best visual cue for perfects, is 'Test your skill', where I personally got the achievement without any trouble. It actually shoves a big text with capital letters reading PERFECT right at your face whenever you get such a hit. It also doesn't have the 60-or-so second limit that 'A minute of perfection' has.

The achievement for getting X perfects in a whole game is obsolete, as you'll eventually need to get 10 in row, which should earn you both. Most will likely already have earned a total of 10 perfects while practicing. Getting 10 in row will take some time, and I consider it much harder than surviving for 5 minutes in the pig mini-game.

TIP: If you're using your own clicks to time the next one, try to hold down the key and wait until half a second or so has passed. This should make it easier to measure the time between the adjacent seconds, as you can use approximate half-second marks as well (as in 'Tick-clack-Tock-clack-Tick-', etc, opposed to 'Tick----Tock----Tick----Tock----Tick----' and so on). You need to be able to hear the key's press and release, of course.

If you got all the achievements, congratulations! You can now call yourself a human clock. If you're missing the one which doesn't fit to the above categories, where you have to lose within one second of starting, just enter any mini-game and instantly press Esc to return to the menu to get it.

Thanks for reading, hope you enjoyed the game!
