this puzzle took me way too long bruhhh, btw you can get stuck in an endless loop, placing a stone that always teleports you into the fire...or similar scenario like that
also tips for dev: you may place some hints? or make a hint with the explanation....
(like something you said explained in comments with):
"Therefore, your first scroll must mean "DESTROY FIRE (CAST)" and your second scroll must mean "CREATE FIRE (CAST)"
u know something like that :3? hehe otherwise I think its too hard
Also quality of life could be to make the scroll smaller and place ist somewhere on the side of the screen so one can see it while casting spells. (Later I got used to it because I casted them like 1000 times(had to restart when I accidentally got myself in a loop, and redo until the last puzzle) idk maybe a delete all block emergency button so u don't lose all your progress when ur in a loop, since preventing the player from doing anything "illegal" with so many different mechanics would be kind of tedious to implement from a developer's side)
but never the less very fun and cool game! :)
also I don't know if I'm actually supposed to solve the last puzzle like that haha was it intended like that (structure wise?) because I think like to get to that idea... wow maybe too hard (if it's really the intended solution idea)
