This was a ton of fun, definitely a learning curve, but I love the puzzles this enables. Not letting two kroniis be in the same room was a really cool idea and well executed visually, I def liked those later puzzles the most. I do think a couple smaller tutorial-tier puzzles at the start would help with the learning process, just to isolate teaching each thing.
Only bugs I ran into had to do with doors sticking open, happened in the first level which let me bring the orb forward (and made me think I needed to), and happened in the last level which forced a restart then also made it doable without clones.
Even if you didn't get to a few things, I think as is this is already a great proof of concept, well done
