I enjoyed this a lot when I had a good run. The art was pretty nice, I really liked the designs for the units/giants. I also absolutely loved the audio for this, the music felt very fitting and the sound effects for the attacks felt impactful/satisfying.
I would have preferred if there was a start menu of some sort, it caught me off guard a bit when it jumped straight into the game. This is definitely a minor thing, especially considering that the player isn't required to take immediate action. Also, in its current state, it feels like the game is very heavily dependent on the RNG. I understand from other comments though that you are aware of this.
All in all, this was a nice submission and I'm glad to have played it. Hope to see more from you in the future!
