started having an issue (dunno if it's mac specific or not) where it would stop responding to certain click interactions, preventing me from progressing - at first i was reloading from checkpoints to reset this but as this became increasingly frustrating during the puzzle across the last two screens i nearly abandoned the game right before the ending before thankfully managing to restore functionality without resetting progress by repeatedly toggling between fullscreen and windowed mode.

anyway it's another samorost.
