While a great game, the 'dictionary' used is very hit-and-miss. It accepts some proper nouns, yet very few of the valid words with difficult letters such as X and Z. I recommend coding it to pull the wordbase from something like dictionary.com :)
To gain any badge on this game with no effort whatsoever build a tack shooter at the earliest possible crossroads on the level. Use the TAB key to select faster shooting and hold down the ENTER key for a minute or so. Your money will run into the negatives, and appear to be rapidly increasing. Start the wave, and now your single tack shooter is strong enough by itself to beat level 50 on Hard without letting a single Bloon through =)
The enemy has one general, when I have two tanks and two waves of rifleman right at their trench... and my men run out of morale? What kind of sissies are these guys?
Great game; reminds me of Half-Minute Hero. However, there definitely needs to be some coding to ensure more Grim Shops. I've gotten to ten dragons in runs where not even a single Grim Shop has been on the map, making it impossible to progress. Weaken the dragon, or allow for more Grim Shops and it would be one of the best games on the site =)
