Hello, it's the first time I've played, I've tried to find people who have played before but it seems that it's not like that, I don't understand what I should do with the cube...(I love the game)
It's normal. my bad, i don't explain any mechanics in the game. Here is two functions of "cube" 1 - open (access to) doors , 2 - use as projectile. And about mechanics . You can speed up and wall jump (you jump higher when you faster).
how to access the doors? I don't know if there's a button (which I'm still looking for- wait a minute, someone completed the game... I probably have to download it, because completing it online seems difficult.)
"Wall jump"
