Thank you for your very detailed review, it's been a pleasure to read it! I'll try to answer quickly:
The level you've been stuck at (level 6) is easily doable but quick response is necessary, You need to click the orb on the right in the first few seconds of the level, the torch will light up and the wall block you, but it'll come back in place after I think 6 seconds, so you have enough time to get to the final orb. It's meant as a simple yet clear teaching that: Torch can be lit up / Torch move walls that have the blue lock on them / Those walls can come back to their original position after a time.
Sorry if that wasn't clear enough. (Also I advise running in fullscreen mode, we didn't know itch.io's formatting beforehand so it's messed up and can crop the game if it's not in fullscreen).
Don't worry, come back rating us when you can, it's kind enough to want to rate back the game already!
Thank you very much and good luck for the Jam!
EDIT: I played the game on another computer and it appears that if the game is lagging out too much, the wall doesn't come back in place in time... This is fixed if you play in computer mode (with the .exe file that we made available to download). We'll make sure to not repeat this error later, sorry about that!
