Thank you for playing!
And stupid me, of course that's a softlock! I tried to prevent softlocks as best as I could, but I totally missed that one.
The purple cloud thing is something I was aware of but didn't change (didn't see a quick fix), instead I designed the cloud pattern so that (hopefully) only one type of solution is possible (though abusing the buggy cloud behavior is not required). Would you mind sharing your solution, if you still remember?
Edit: okay the purple clouds are actually more bugged than I thought (And I'm not sure it's something I can fix, considering the limitations of realtime puzzlescript), I'll have to try and redesign the pattern to only allow the intended solution
Edit 2: Okay I did (hopefully) fix it, was just missing something obvious :)
