This game was so much fun! I used to play so much Super monkey Ball as a kid on my Gamecube. This brought back some good memories!
If I may ask, how did you achieve this pixelated 3D look with Godot? I'm really into the style, it reminds me a lot of the 'A Short Hike' game style where you shrink the resolution of the game and point a second camera at that (that's how it was achieved in Unity at least). Cheers!
