Great Defense Game
This game, with only seven towers/structures available, exceeded all of my expectations.
Ironically, the limited selection made the gameplay quite difficult. I lost on the second level at least three times in a row due to poor strategy and tower placement. It became apparent very quickly that the meager construction options meant that each and every tower must play a critical role in the overall defense.
Some of the more unique features of the game include an auto-upgrade system and achievements that actually benefit the player. The auto-upgrades appeared to be a setback at first, because I felt that a manual system would test the player's strategies and decision making to a greater extent. But, I discovered that the auto system presented a dimension of strategy in its own right. For example, I would oftentimes get caught between a risky, early Cannon Tower strat (for greater firepower) and the more reliable, mass Archer Tower strat. Again, the small selection made each tower crucial, and I found myself losing to the very last enemy or barely squeeking by on more than one occasion.
The fact that the achievements boosted your power - instead of just boosting your ego a bit - was such a pleasant surprise. Yet, I felt that the game a bit too easy as I amassed those shiny trophies. In this sense, Level II seemed much harder than Level V because by then I had all of those nice perks working in my favor. That being said, it was still an innovative idea and a big plus in my book.
Overall, you guys did a nice job. It would have been nice to see some arrows and cannonballs flying across the screen, but I supposed that would've lagged things up quite a bit. Great work, and props to Maestro for the fitting soundtrack! [5/5]
