Biggest complaint, no WASD movement. Easy enough to implement both control schemes simultaneously.
Short game. Basically it is as if tictactoe was built by a historically gladiatorial caste system. Collect the stars, get a high score style arcade game. I did the math and determined that there as a point at which the player cannot win because all liberties are covered by a projectile object; as the speed of the objects increases over the course of the gameplay.
Not sure if the frequency of objects appearing resets after each run. Found that if you sit on the game over screen, you can see how the randomly spawned obstacles progressed their spawn time delay. Not sure if this decreases all the way to zero.
Either way, not bad for a simple game. I would like to see a larger playfield at some point.
