An absolute banger of a game, very well done! Textbook introduction of game mechanics. When I came to the clouds I thought it couldn't get any worse, but then I was met with a new mechanic. And when I thought THAT couldn't get any worse, I tried challenge mode. Goodness gracious!
The only thing I missed was the ability to pause the game during a run. Otherwise the game made me smile a couple of times and I had a good time playing it. Very much worth a try!
