✦ Nice Slice is a simple fruit slicing simulator with a total of 30 Steam achievements.
✦ Gameplay is all around of a single button: LMB (left mouse button).
✦ Your objective is to cut the fruit without failing to increase your multiplier and score, but score isn't needed for any achievements so we will focus on the achievement requirements instead.

✦ All achievements are tiered (each one consists in three tiers) and can be accessed by clicking on the star icon in main menu or after finishing a match.
✦ You won't get progress for an higher tier until you've collected the prize from the previous one (feel free to suicide to collect the prize right away).
✦ Don't waste your tokens on skins as they're useless. Instead, save them to unlock new locations.
✦ Achievements won't unlock until the end of a match. If you reset after unlocking one, they'll unlock on the next finished match.

Estimate completion time following this guide: 30 minutes.

Now with the game.
Focus first and foremost on completing all three tiers of "hit the mouse" achievements. For that, simply cut the food until hitting a rat, restart, and repeat. You don't have to finish the match, hitting the rat once and restarting will be enough for it to count towards.
Note: Restart if the rat didn't spawn or if it spawned in a blocked/annoying location.

An example of a good starting location would be:

And an example of a bad starting location would be:
Try to avoid locations like these as they're a waste of time.

Last tier requires hitting 500? rats, but the counter increases in big chunks. I'm not completely sure if this is an intended mechanic or just an unfixed bug.
Some other achievements will come along the way. Make sure to collect the prize after unlocking every new one.
Don't use your tokens just yet. You'll need to use them to unlock a new location later.

After you've unlocked all three "hit the mouse" achievements, do any other easy achievements you have left until collecting 2500 tokens.
Can pretty much spam click on the food to get the achievements; score multiplier doesn't matter when it comes to unlockables.

As soon as you hit 2500, move onto the next level by purchasing it from main menu (right arrow).

This step is similar to the previous one, but with parrots instead of rats.


Make your priority the completion of all "hit the parrot" objective tiers while saving your tokens to purchase the third and last location (5000).
Counters seem to increase at an insanely faster rate at this location, so feel free to farm any achievements out of your way.

As soon as you hit 5000 tokens, move onto the last level (Space Station).

Lastly, do all tiers of "hit the alien" objective in the same manner as the others of its kind and then clean up the remaining achievements if there's any.

Note: Alien location is always the same.
