Bug Found :(
1) invisible crate : it can still pass, if you push & pull it by your sense.
2. platform despawn : just go back into the hole. It will reactivate the platform
3. stuck box : the box in this level is stuck and there is no way to pass. The game end here. Really sorry.
All these bug s are fixed now. and I will upload the full new bug-free version at the end of this Jam so REALLY SORRY :(
