This is Bob

The game's goal is to let Bob
reach the end of road

Road changes, but Bob never gets off

Once he hits the green dot
he goes to next road

Problem is, there are these four rods

If he hits these rods, back he goes

So to make chance for Bob
to reach the green dot

I've put a hole in each of these rods

You can't move road
and you can't move Bob

So you move rods,
'cause that's your job

Try it now
to see how it goes

Your tapping point
is the new place for their joint

By moving joint, you move rods
and resize their holes

Each hole is placed
in middle third

So you should aim this third
to the way of your bird

To move this joint, GENTLY TAP
and be precise

DON'T,
like in most of other games,
brutally swipe

You can take your roads
in whichever order you want

Feel free to raise or drop the speed
if that's what you need

Shapes of these roads are called
polar curves

You can draw them yourself
with a little math
and lots of nerves

There is no "Game Over" in this game

There's no score and "Hall of Fame"

I always hated all of that

So it's over when you want

And you are always welcome back :)

Now hit the road, Bob!

... and don't hit those rods ...
