I love the idea of running away from your past selves XD and the map is well designed too,
As a piece of feedback, I would say it would be nice if you had clearer progression, or if there was some visual storytelling aspect to these enemies being your past selves. But good job overall!
If you can find the time, would you please check out our game as well?
Our twist of the theme is that a critic tries to play your unfinished game, and you fight from inside the computer to make him like it. Hope you'll like it!
