To anyone who sees this comment before an angry mob downvotes it to oblivion about 30 seconds after posting: it's actually quite possible to play, and even have progress, without tokens. It just takes a bit more work. Still, God forbid games actually take some effort, right?
Good level design, neat sound and graphics and fairly enjoyable gameplay, but it really is getting frustrating going the final round levels over and over again looking for hidden cogs.
