Nyamazingly fun and addictive

This game is super fun and has pretty much zero problems. With about 3 very different run modes (and two not very different ones), a pet nyan, an entire CITY for the nyans, a character editor to make your own unique nyan, and my favorite, the huge amount of hilarious and sometimes very unconventional powerups that make you want each run to last forever. Take care of your pet and your city every so often and you’ll get coins and fun skins and backgrounds for the main gamemode. One thing I'm glad of is how you removed all smoking and drug references, but nyan cat still occasionally swears when you touch the dog so maybe you could remove that because you put this game as 4+. Fun game mechanics such as the milk multiplier, fancy gems with extremely useful powers, and sticks of dynamite that you need to tap to deactivate make the game unique and even more addictive. This game is the one infinite runner that never gets boring for me, so I hope you continue to add new powerups and new modes. The character creator makes collecting coins always important, and I like making my nyans look like the cats from Yo-kai watch like Jibanyan. I'd like if you could customize the legs and tail more other than color. Also, nyan cat is obviously a boy and tac nayn is probably a girl because of when you get the adrenyalin powerup.

Terrible is this game ,

SUPER addicting! 🤩

I personally LOVE this game! 💕It’s super adorable and whenever I have free time you’ll catch me playing it!❤️I love that you are able to make your own pixelated Nyan Cat. The whole thing is very clever! But there is a downfall. Many of the reviews are about lag, too much ads, etc. I understand what they mean, BUT if you think about it, doesn’t every game have that?🧐I know that it is frustrating to watch an ad every time you die or complete a level. But there is a way to fix this problem! If you are sick of watching these ads, all you have to do is turn off the internet! (Only if your game doesn’t run on WiFi 😅) And that is the only problem about this game! I concentrate a lot on Nyan Cat, making plans to try and get every single coin. But the game is too smart for me, having some way of beating me. I’m forced to play again! 😂 Here is some advice to get far on Tac Nayn! Try not to get on bars with dynamite, invisibility power-ups, or energy drink. These will guaranteed make you die. I hope this helps you!
