sorru for being late(reading this?). you need to carry a flag to belt conveyers to go through spikes
You need two alive cats and one dead cat in the lower part.(2 cats are required in the bottom room)
P.S. By the way, I played my level of updated version but couldn't solve the last map(it should have a solution). Difference from original version is the amount of spikes. I recommend original one. (Editing starting point enables you to play only the last map) If you wanna try updated one, do so.
