way too many ads. i already know that ads help you devs out but when you play an ad after every 2nd stage it just gets to where the game sucks. youre just saying, "hey! you might wanna check this game out", and you can do that by playing the ad 1 time and giving us time to enjoy the game, say 7, 8 minutes or so, before you play another one. for real it burns us all out when you all bomb us with ads. other than that its fun but i just want to uninstall. its no fun playing when its congested.

UPDATE: AVOID AT ALL COST. This game is THE WORST. It starts out great, the gets progressively IMPOSSIBLE. To the point I'd call it a scam. This COULD be the BEST of the Smash games, BUT it has ONE FLAW, but it's a big one: the levels are impossibly hard. The farther I get into the game, the more ridiculous it gets...almost to the point of quitting even though I paid to remove ads. I'll change my review to 5 stars with improvement.

love the game. but having commercials before you even get your points is ridiculous. even if you're not forced to watch 3 minutes of commercials, I still had to watch one. and its every game. that's greedy. you suck. edit: finally got to a level you can't win without watching 4 minutes of adds to get enough ammunition to win. deleted.
