A cool trip in a (not yellow) submarine with a team of time travelers scientists embarked on a quest to save some children from a witch in a mountain.
The pretty visuals and the great soundtrack give a good mood to this adventure that I found quite relaxing to play after work.
I also loved the voice acting (with the british accent) that really helps bring the characters to life.
Puzzles are well balanced, it took me about 7 hours to finish the game without the need for a guide (well... except maybe once, but no more I swear!).
And a last word for the dev who is still active on the forum and helped me out with a problem I had with a DLC, thanks again!
