Fun little platforming game starring a cute fox! The character feels nice to control, the levels are well designed and fun to go through. The rising lava and the fox character reminds a lot of Ori and the Blind Forest, wonder if you were inspired by that game.
If I have one criticism it'd be sometimes, the background and the platform blends together, it's a bit confusing on what platform you can jump to and what's just a background image.
Other than that, good job!
