I really appreciate honest feedback. Also I'm glad you got the point of the trail, didn't think anyone would get why it's there :D Was it hard to get a hang of the game mechanics? Because many people have said I need a more detailed tutorial in game
I found it really simple to understand. One thing I should improve is line up the direction of the level with one of the axes of the player. That way you don't go diagonal when just pressing one arrow key.
