Once I learned the first few mechanics I couldn't wait for the chance to combine them and it came very early, thank you very much.
I liked how some puzzles look like you're just repeating a previous solution but it's actually teaching you a new one - though as I wrote that I found the level I'm referring to (the one that's fire heads all the way down) was actually the last one, and instead of an easy solution teaching me something new it suddenly read as an unchallenging final level.
I think the adventurers could have been designed to read a little cuter (I wasn't sure if they were supposed to be actual babies or not, mainly since their outfits and bodies are more visible throughout the game than their faces which look the most 'cute') but that's such a minor problem.
My main problem was the left/right rotation tiles were difficult to use since directions change with the direction the adventurers had already been spun - once I started seeing them as 'clockwise' and 'anticlockwise' it became easier, but maybe leaning further into that instead of cardinal left/right could have read better.
Very good game, I enjoyed it!
