this is nice and fun, the only problem I had was that rewind interacts with the boxes. This caused my character to not pass level 3 or 4 - with the box through the right portal into the upper left. But otherwise, it was a nice and simple fun game. Reminded me of miniclip games when I was younger.
This might be cheesy but I would appreciate it if you could try my game out as well 'You Are Alone'. Many thanks
