The guy I saved in the second stage pushed me across the stage as he said you're my hero, and on rhw later level, pushed me towards the enemy killing me as he thanked me. Cracked me up! I beat it and they all hailed me as a champion! I loved it!
I clicked on something offscreen on the right on the 4th stage and the whole screen went blue, and stayed like that (but it was still playable), and then I clicked something offscreen on the left and it fixed it!
