story-line is paradoxical nature in time travel this is aswm!!!

For what it is, I like the idea a lot that the player has to type in a year. Would be really neat if you could "by accident" travel to the wrong year, by typing in a different number. Even if this is your very first game, it would make the game already feel more polished if you check if the text is readable nicely. Keep it up!

I think you are new at game development.  You should improve character movemont and animations. Also you need to improve the design of envoriment. But don't lose your hope.
