in terms of 'Games Design' I would say its a top job. he/she has proberly planned this out or worked on it from start to finish and they have ended up with a working title....

yes ok it might not be the best game graphically however if the title works without bugs who cares?

However, Yes somone does care if they are selling the title it does need polishing.

overall though nice job.

I dont even have a fully working title yet and neither do alot of members on here. even if its using a different engine or not.

The concepts are very much alike depsite what engine you use. (design, planning, etc)
