Love the concept. Nice looking game. Snappy. Challenging. BUT ...
It's very frustrating when you're working on a personal best score and you run into something like "FULL PROOF PLAN" when, clearly, it should have been "FOOLPROOF PLAN". I have many more examples like this. Some items are just plain misspelled.
They also allow players to cheat the high score tallies. It's very difficult to progress to rounds much higher than 60-70 but it's not unusual to see impossibly high scores with rounds as high as the 200s.
They claim to periodically clean out obvious cheat scores but I sure wish they'd pay a bit more attention to the player-submitted items that make it into the game.
