The concept is quite fun, and the way the AI reacts to the player moving in a diagonal adds a lot to the gameplay. Adding different shapes in the later stages was a good idea too. I think one big problem is that restarting the audio at every death feels really spammy for the first minute or so, having like 5 seconds of silence at the start of the dialogue would prevent this. Also, i guess you just didn't have time, but the absence of a main menu and a button to exit the game at the end makes the experience hard to stick with for the average player.
