The original Nyan Cat* as a custom level for the 3DS game Pullblox (EU) / Pushmo (USA). Available in 3DS e-shop for 6€/$7. You should all get it, it is a great game!
If you own it, scan the QR code to save the level. I am really happy with how this came out. This is a very action oriented level and if you own the game you should definitely
try it, whether you loved or hated Nyan Cat!
Difficulty: Pretty easy / Normal.
*The tail is a little bit shorter because of size restrictions.
