I've just played 5 levels for now but have to say the game is so cool! It contains very interesting puzzles by their own. However adding "ichor" mechanic is so clever I just had to write this comment. Great job! :)
Two minor suggestions from my side:
1. I've watched gifs before playing, so when I started first level I immediately solved the puzzle without touching tutorial. Then I was little bit confused why I can't click my green "ready" button. It turns out I have to go through the tutorial to do this. I think you could make tutorial optional or make it more clear it's still not finished.
2. You introduce new element after every level. This makes the game super condensed which may be fine for many players. For me it was too dense though. I'd like to have more levels with newly introduced element to get familiar with it, know it's good and bad sides, discover which synergies play well on various levels (e.g. open vs tight level). It's a lot of work I know, but you could turn it into fully functional title with several worlds that have their own flavour and maybe own "ichor" goal.
