Spoiler: Intended Solution Keep the cross upright and move it slowly to grab the lower stars. Put it in the gap next to L so he can walk across to get the star. The higher stars will require throwing the cross around. Use the slope to make the cross higher.
My friend, it's very good that you are experimenting with different types of gameplay! I love FD levels. That's probably why it's so easy for me. But I am very glad that you try yourself in different genres of mekorama. Variety is always good. Thank you
