Well first of all I did enjoy Max's World, and I liked the art style, although it was a bit static at times, and I did like the overall presentation. I do wish that there had been some music of some kind though; obviously not necessary or anything but it would have been nice.
The ending felt a little abrupt, and maybe could have done with being stretched out a little longer because it snaps from the ending to the credits remarkably quickly. On top of that I kind of couldn't figure out how to exit. I don't play many things using Unity so if there is some special way to exit, or if I missed something incredibly obvious, then I must claim ignorance there.
Overall, this was a rather sweet, simple and calm little game that I enjoyed, and the little guy with the sword and shield reminded me of the first monster thing you get in Ni no Kuni... and that made me smile, ha ha.
