Hey Smango! I don't know if you noticed, at the first cube part, there is arows indicating where you need to jump, and at the final cube part there is no more arrows indicating where you need to jump. (Sorry if my english is bad, i am from Brazil)
instead of making another part on the last day instead try to make each part better instead of it being straight slop so basically if a part sucks for you u can reimprove it but thats my idea so idk if you might agree with me
