Thank you, and I don't mind at all!

I don't have any professional experience but I did build a pacman clone in Turbo Pascal (on MS DOS) back in the 90s. Also I've been playing games all my life so have a feeling for what's important - collision detection, walkable/collidable areas, speed/timing, some basic NPC logic etc. So that seemed to have been sufficient in this case :-)
