Jeff Mumm - Invidious

Hi there! My name is Jeff. I'm an animator and solo game dev. I'm making the completely hand-drawn parkour platformer game Guinea Pig Parkour. I also like making lots of fun little guinea pig animations and stuff for my art shop!

If you want to support my work, you can become a patron at Patreon.com/GPigParkour or go to my art shop at GPPshop.com !

Silly drawings are still being made!
Updates have just been paused while I work to get a nice chunk of gameplay done. Stay tuned!

Speechless at this incredibly generous donation today! Especially since I haven't even been active online for months (which I hope to remedy soon). I'm always amazed at the impact GSG had and the number of people who now say they watched as kids. Thank you so much Mousefan11!!

Officially one year left of my 30s. GPP started the year I turned 30. It's been quite a ride, and it ain't over yet! Learned a lot, made a lot of mistakes, but I'm so grateful to be able to pursue my dreams. 2025 will be a year of updates, can't wait to share what's next!
