He hit the nail on the head. I do give extra points for having a reshuffle button. But, yeah...this is a game template game makers just pull out occasionally, like turret defense games, and just rehash with different art. Gets old. But looks good. Plays good, too.
However, to play devil's advocate, the folks on NewGrounds tend to see a LOT of games...we're sort of like movie critics. We're going to get tired of the same old stuff quickly, since we see it day after day (for those of us dedicated enough to slog through it all every day). For regular folks out getting laid and doing something productive with their life (*cough*), they don't see games like this often enough to get bored with it.
I should do something productive with my life. But first I have 10 more flash movies to view...
