Honestly, the last zone forces you to maximize upgrades into the bats and passives. The mines are far too wimpy to even help; I've always LOST speed by hitting them. Put more stuff in the end zone so we can actually get places.
The matchmaking system needs a serious rebuild. Newbies should versus newbies, and not face a rank 2000 player that they have no chance of winning against.
An interesting take on Hangman. The addition of bonus guesses for every extra correct letter after the first correct letter is a big bonus, especially when you can finish the phrase. The puzzles in later levels become challenging, with you having to use bad guesses and/or parts of the level that you have toggled physics on. Bombs are a great way to solve some of the puzzles quickly. One of my very few gripes with this game is with the gravity on your character. It seems a little too strong. Other than that, it's pretty good.
