This game is really frustrating. Second time I get an impossible curve right before reaching 1000. I definitely won't be playing the second version of this game if it stays like this.
It's a great concept, however the developers need to work on the cross-platform side of things. I find the game to be laggy (lots of delays when entering/exiting levels) on my Mac, and it's even crashed my browser twice because the Flash has gotten caught up in something. It seems to be fine with my Windows VM. One note: it wouldn't be a bad idea to have a corner "% loading" when entering new areas, so that people know it is loading. Another note: the game is awkwardly sized for me -- I had to increase my zoom level to see the bottom part of the game screen.
The game isn't bad, but the server really needs upgrades. The majority of the time, I disconnect when I'm doing well (never when I'm doing poorly) and can't log in. Without an effective way to save the decks/etc, this game is pointless. Beef up the servers, or switch to saving decks with sol files that save the account name/id in addition to what's there, to ensure that people aren't sharing.
How will you know if it's the same unless you play it! Seriously though I'm planning on balancing things out much better in #2 :)
