Thanks for the rating and sorry you couldn't finish it!
We as a studio are believers in the idea of just dropping the player straight into the world and letting them figure out how to play on their own, by hidding the instructions and tutorial directly into the world, for example, in the form of hieroglyps that are scattered on the starting room and the only accessible room from that point.
So after just a little exploring and paying attention to surroundings the controls would become clear.
Perhaps in the future we will add a small tutorial as a small interaction of Kiwi with the hieroglyphs, having him turn to look at them and commenting on the controls themselves, but a way to make the controls themselves part of the puzzle is what we personally like most.
