hey thanks for playing! here you have all the game controls in english:
← / → : lateral movement
↑ : interacting with nearby lever + speaking with the npcs
space : jump
X : picking up + releasing objects from inventory
Z : throw arm
A : release + pick up arm 1
S : release + pick up arm 2
D : release + pick up legs (if you are on a platform and press D you will join your legs to said platform, with shift+D you'll switch control to your legs and carry yourself with the platform)
Shift + X : kick ball if you are in front + throw ball from inventory
Shift + A : activate lever remotely when you have your arm joined to a lever
Shift + S : activate lever remotely when you have your arm joined to a lever
Shift + D : switch between legs control and body control when you have your legs joined to a platform
-----------
the problem you encountered with the levers input may be a bug we already have issued on github so we'll keep an eye on that
pd: we are considering translating the game into english over the summer so nobody will miss the story that we put so much effort and love into, hope you'll stay for any updates!
