Cool Way To Learn; Too Expensive To Continue

I like learning about the engines with this, but the cost of $3.99 is just too much for 3 extra engines. If there were more included, or the price dropped I'd give it five stars.

What if you don't have Facebook?

I don't use Facebook. So then what. This is a joke and not worth the time to download.

OK but requiring a Facebook "like" is really annoying

It's a poor practice to force a "like" from users just to see much of the site in action. If you are not on Facebook you cannot see the 4-stroke simulation at all! The steam engine simulation is otherwise the only free bit. It is basic but useful and the graphics well executed.
