This was a fun game to play! I'm curious, how did you go about creating the hole? My game also features holes in the ground that the player can fall through and my approach was to use a shader for the hole visual then a trigger to play an animation. I'm wondering how you did it for your game since it didn't seem like you were just disabling the cube colliders because some of the cubes rolled in rather than just dropped straight down. Anyways, it was fun to play. Hope you'll check out my game too!
