I'm sorry to hear that, didn't have enough time to test out all the bugs and fix them, you can make the ball touch spikes and it will respawn the ball, as well as that trolley thing, thanks for playing :)
oh I get it, the thing is that the trolley doesn't really respawn, it just changes position to its initial position and rotation stays the same, so I guess if it is rotated like at least 90 degrees either way, and "respawn" happens it can get stuck. thanks for the feedback, it was really helpful.
