Amazing work! I love the presentation, the Last Stand effect makes all the environmental destruction even more satisfying. Most jam games would have stopped at the initial area but this one keeps going, and going, and then reaches a satisfying conclusion.
I had to turn the sound down in order to hear the voices, it drowns them out by default. Some enemies in the first area are oblivious to the player while within visual and shooting range, which isn't necessarily a bug (and certainly was helpful for me at the player) but it's unclear whether that's intentional or not.
I really appreciate the checkpoints, the super shot and the Last Stand's slowing down time, all of these were absolutely needed (by me) to complete the game.
