I'm going through the tutorial stage, and on Stage 15 where you activate the magic wall to turn the amoeba to gems, it instead turns into stone on many attempts. I do not understand the mechanic causing this and there's nothing I can find in the game that explains it. Can anyone help me understand this?...

I think Tutorial 18 is bugged for me. I go through this series, the stones fall onto the slime, but... nothing happens? I guess that's not how it's supposed to work, judging by the videos I've watched online.

I've installed this and tried every key on the keyboard. Nothing moves the character around. There are no settings for keys either. How do you even play?

Any idea how to approach this? https://steamcommunity.com/sharedfiles/filedetails/?id=3563400048 I see now way to get near the diamond without letting it explode!

Do I need to finish this one with at least one star to get the achievement badge in steam that I finished Crystal Heaven? As I finished all 20 levels, but only Amoeba's Disaster with 0 stars. Or do I need a min. of overall stars ?
