Hey Ella, thank you that's excellent feedback! Glad that Edge finally believed me xD I guess it's because there's another file additionallyfor the physics engine I use.
The thing with mochi was bugging me (and others) as well, I changed the behavior a bit so it's now pretty guaranteed to save the ball (how it was actually intended). Another playtester mentioned that they expected the upgrades cooldown to refresh when you upgrade it. I'll do that next and see how it goes. Thank you!
