Very interesting and original game! I really enjoyed playing this, good job!
Only two problems I had were that on the small pillar things, I sometimes could not jump (probably ground check that doesn't work 100%), and placing clones is not very clear (I always was hovering air while holding the mouse button, but you can only place one when you hover the ground)
Aside from that, very cool game with interesting mechanics! I hope this gets developed further after the jam!
