The jokes in the Temple of the Panda were so difficult for me to get, I wasted a lot of energy getting answers wrong until I reached the correct ones. Good thing I had leveled up shortly before.
Re the joke about the programmer who's grocery shopping for his wife: She says, "Get 2 sausages, & if they have eggs, get 10." When I guessed 2 sausages & 10 eggs, I was punished with 3 experience chests disappearing & three 1500-energy tiles blocking my way. The correct answer turned out to be 10 sausages.
Re the joke about the policemen & the power outage, I got that one wrong at least once as well. A person being stuck on an escalator for 5 hours sounded ridiculous to me, but at least I got that one eventually.
Re the joke about the boy & his grandma, I got that one wrong TWICE. To a response like "LOL noob," I thought, That is one cruel grandma!
I would prefer that nothing happen when we get answers wrong, instead of being punished with high-energy tiles. The game is hard enough as it is!
