All ideas are cool because they implemented by you! I liked thoughts mechanic a lot. I am not sure that 4 and 5 variant fits into your style. So, 4 and 5 are quite risky but interesting from experiment side of view. 6 is my choice. Then 1 and 2. Then 7 and 9 then 8 and 3. So
6 top place!
Tier 2: 1 and 2
Tier 3: 7 and 9
Tier 4: 8 and 3
Tier 5: 4 and 5
