Your control scheme is strange and unintuitive, but clear enough from the description. The issue, however, is that the game page is larger than my screen is tall, and not locked in place, so attempting to move the ship with the scroll wheel results in scrolling the game offscreen! This makes the game extremely difficult to play, and not in the good fair way.
I will note that the english text in the tutorial says to shoot with the right mouse button, but you have that bound to the left mouse button (not sure what the russian version says, so probably check that one too)
