The labyrinths are not that difficult to create actually. The hard part was creating a level editor. Now that the level editor is done it is relatively easy to create the labyrinths. You are right, I have no idea if anybody will be interested in a game like this. I imagine there are people that like these types of games so I'm counting on that. It is a gamble. Worse case scenario I will be able to reuse a lot of the work for my next game, especially the level editor.
>>It could be fun if I race faster of course - what about having special items to be able to zoom out and take a peek at the whole map<<
I've been thinking about doing stuff like that if it will make it more fun and doesn't increase the scope considerably.
Thanks for the comment.
