Great combination of ideas!
4/5
I was pleasantly surprised by this. I was expecting a cheap Pac-Man clone and instead I found a very clever combination of two different games.
The graphics were adequate, maybe a little on the small side. The sounds were appropriate but sparse. Some tense music would really add to the excitement of the game. And the controls were just slightly off. These aren't huge concerns, and they can easily be fixed in a new version. (And I definitely want to see a new, improved version!)
But it's the concept and gameplay that really made this work. Good job.
