I really liked this game. I really loved the mechanics of switching to the mirrored world and switching the dinos, to outrun some obstacles. Probably just my head, but I needed time to get used to pressing the right buttons for switching and/or jumping at the same time. So maybe changing the keyboard layout a little can help here. But other than that, this is a great game and I had lots of fun playing it.
Also liked that there was a level choice :D.
