you need to select if you see, hear, or move
by default you are seeing, in order to move you can either press 'm' or select the option in the top left screen
That's not what I meant, while having the Move option selected the player wasn't jumping high enough to go forward, this issue come from how you move the player which need to be moved with a formula like: Direction * Speed * Deltatime.
First: thank for trying the game :)
Second: No, it's not deltaTime, it's physics based. So it's all rigidbody movement and forces, not frame dependent.
