This is a very good game. To anyone who have not played it yet, please try to spend a minimum of time in it to fully appreciate it.
This game is very well executed despite appearing like the banal plat-former in the very beginning.
The level design is smart and I really loved the small little details. Like for example, the work done on the audio where the music subtly changes between levels. This just reminds me of Banjo-Kazzooie where the music blended into different version as you go underwater or enter into specific sections.
The hints are smart as well, they don't give you the answer straight away, they just invite you to look where you should so that's just the right thing to prevent you looking forever at a place that's not revelant.
I can't say more on the theme than that you just nailed it!
Thanks for making this, I had a lot of fun playing it :)
