There is friction, angular momentum and we are thinking about custom obstacles and maybe even custom shaped balls in the future, all of which makes it harder to go with custom physics. But I've also been thinking about it as an alternative yeah.

It was suprisingly easy to connect Godot and Anki through git.sr.ht/~foosoft/ank...
I feel like there could be some very cool projects that can use this integration to gamify the notoriously boring Anki more

Haha yeah the web build performance is pretty questionable. You can disable the VFX (which has some costly fullscreen shaders) to save your battery. Otherwise we are working on more consistent Android/IOS builds!

Honestly I'm glad it even works on IOS lol as it's kinda unreliable. We are working on a native IOS build, which should hopefully be a lot more stable than Godot web stuff :)

Try it here, the password is "balls"!

Honestly it's super cool how fast you can make something vibe-y and playable in Godot. Environment/terrain shaders are super nice to setup and I can restart as much as I want to make sure to get all the values right.

thanks! that looks nice actually
