Oh hey Don't Starve is big enough to have bad shitty made clones that bluntly copy the game...
I just wanna warn you, Don't Starve is so popular because of a fantastic art style, good music and brutally hard but entertaining Game play...and you will not be able to surpass that if you artwork looks as...bad and generic as it does here...can't judge the game play from here to much but seems not to promising as well. And the music...*sigh* it exists and does not like the rest of the video annoy me...even if it is simple and uninteresting.
I am sorry if this sounds to harsh and hurts you or the persons you do this with, but as someone who only bluntly steals and does not improve or experiment with the things you steal I fear someone has to tell you that this wont be of any worth or interest if it only is a bad version of Don't Starve.
Maybe I am wrong and you plan do do a lot of amazing things with the game...but if you plan them then put them into the trailer and not the parts you stole from another game...
