The games is good. Its buggy and has a lot of problems but has a lot of good in it and can be expanded into a larger better game
First, the artstyle. The rough paper sketch art makes this game charming. Then the time travel thing is pretty good and the the music is awesome
Things that could be improved are the fonts in the game, some aspects of the time travel mechanic and some more things but as it was made in 7 days with real life stuff, so I can't blame you
Also when the left arrow, is pressed you could set the moveinput value to -1 or more, so that when the left key pressed you face left
But anyways I'll rate this game a 3.9 out of 5
