Level 7 - put a block in the middle and trampoline over the stationary green blob on the left. Then let them go all at once. Some will die but enough will make it. "Restore the balance" - You have to fill the pool with green blobs.
I found the second level confusing. The shift appears to be leading up into a tunnel so I stood there pressing shift and expecting to go up or something to happen above. Turns out shift is dash.
Ok, I wrote a Python script to solve #23. The solution is simple but not at all obvious. Also, this was just for fun so don't lecture me about code reuse please and thanks. https://pastebin.com/54aZ4awy
Thank you! It was done without maths (I'm not good with them :P), I created the levels by exploring/joining the mechanics in some interesting ways and with a lot of trial and error.
Suggestion: have the player calibrate the darkness before the game really starts. Until I adjust the settings, everything is pitch black without the flashlight.
