Getting 65k is not that hard, just keep in mind you don't have to kill the creatures to keep up speed. If you can avoid getting hit, it's really rather easy.
I really enjoyed the game and I think the medals are spot on. I would love to see an impossible medal though, maybe at 100k. Now that might be hard.
Fun, but doesn't really hold a candle to the original in my opinion. However, I can't say that I fully experienced this game because the overload on dialog caused me to just skip most of it. I realize I probably should have tried to read through it, but I did find "The Company of Myself" dialogue much more engaging/interesting.
Just my 2 cents though, I did enjoy it!
Energy systems sucks.. do you really make that much more by requiring people to pay for your crappy card game.
It's actually pretty fun, but the energy system literally ruins it.
