A new version of Tontie (v.1.0) was just released a couple of weeks ago, and it now offers even more features and enemies than the beta (v.0) had. The first noticeable addition is the randomly appearing treasure chest filled with coins, hearts, or even a laser gun that is good for blasting anything in sight. I was lucky enough to get a silver hammer in one I found.
The new version is both easier and more difficult than its predecessor. It is easier to access the hard-to-get items like the better quality hammers, extra heart containers, and the new laser gun via the treasure chests, yet the game is more difficult from the resulting mayhem that is unleashed upon the player who is then able to progress further into the later levels. Each new level presents a new type of enemy with its own rules of engagement adding complexity to the mix.
Control in Tontie is best with the numeric keypad, simply press the appropriate key as instructed for each enemy. Some enemies require more than one hit, others require hits with precision timing, and others instruct you to hit a different key entirely than the one it appears on.
