Well Done! It was really like fall guys levels.
In the intro level, the text was too bright. It wasn't pleasant to read, at least for me.
I had some issues on the end of the first level. Some times I would just respawn before even trying to jump to the moving platform. Once I respawned after landing on the platform. Was there a limit of ball hits you could take? If yes, then it missed a hit feedback. Other possibility was the respawn trigger was too close to the ground and caused overlay events for the player, or even for a lost ball, while the player was on the ground.
From what I've seem in the source, the random restarts were caused by some balls entering the Level_Restart_Volume. To fix it I added a cast node to check if the actor causing the overlay was from player class before doing the restart.
