You could make it more varied (not just the roads) , i'm not sure how the editor you use works , but different quotes and sayings based on how many roads you have traveled or after passing a certain point , different enemies or how they act , it is fun but the repetitiveness is what lets it down. (i understand it was made in 10 days so i'm not bashing you , it was a good effort)
As to whether you continue it , that's solely based on what you wish to do and what you want to gain out of it. (make a bit of $ , or gain some recognition for a fun indie game etc)
