This Penko Park fan art by a player's daughter melts my heart 🥰
It's all there: Logo, level symbols, even the "photos left" counter in the corner!
Penko Park is 30% off on the Nintendo Switch: nintendo.com/store/products/…
Very proud of this version of the game!
It was a massive effort to optimize it enough for stable 60 FPS, and it took some more ingenuity to figure out how to craft good gamepad controls.
Check this out if you're into wild, experimental and all-around-awesome fonts!
@LucasDescroix custom-designed all the fonts for our games Wunderdoktor and Penko Park, and we couldn't be happier with them! ❤️
