Wow, such an interesting entry actually ! I think this is one of the most polished one i've seen so far ! I really liked the art, the music and the global atmosphere
However, as mentionned in other comments, yes this game is indeed really hard. Actually it was not a big deal for me to try every option that i had and i had even quite some fun discovering all of these but the real issue was the lava ... It was so damn frustrating not to be able to discover and just having to rush ... I think implementing it after a while would have been better
For real i'm so frustrated i really wanted to play more but it was too hard x)
All in all this is a good job, keep it up !
