Very nice game. I love the art style and the storyline and dialogue, very funny.
It made me curious to continue playing to see what happens next. The whole "man from the future" thing was a funny twist to the story as well.
The UI is very nice too, well it is the main game mechanic if I'm not mistaken.
The only thing that I could suggest, is to add maybe a walking animation and animations in general, otherwise congrats on this game! You did a great job!
