Oh right, why didn't I think of giving the player nine lives? What an oversight! (Please don't give me a zero rating, ahhh w(ﾟДﾟ)w)
As for the stool, I actually just placed it there randomly. I never expected it would be such a huge obstacle for most players. Level design really requires much more attention to detail. I've learned a valuable lesson from this! (´▽`ʃ♡ƪ)
