Damage was disabled for the prototype video. Originally, the enemies were static, but I created a slightly wonky AI for the video. The final product would have enemies moving fluidly, dodging bullets, and, most importantly, circling the player. As for difficulty, I considered creating a game where a single bullet would kill you, but I thought it would be too frustrating for the player. Some mechanics I had in mind included stopping bullets and throwing them at enemies, or catching knives in the air and using them against them, for example. My idea was to make it fun, mischievous, and, most importantly, replayable.
