Clever, clever mechanic. Really cool that you need to go backwards after you finish the first run.
I got the neutral ending, I guess it's because I didn't pick all the coins?
Nevertheless, I really enjoyed the game, sound design was good, graphics were neat, game design is really clever like I said. But, I didn't really feel much of a threat from the red circles. At first I thought I can't let them touch me, but afterwards they were a way to progress (which was cool, I just think you need to seperate the two personally)
Well done!
