This was a really cool idea and put me in the mind of Shin Megami Tensei, where you can either defeat demons or try to recruit them, but at a cost to your health. The programmer art was really cute and the shooting and movement were really smooth. I did encounter a few bugs, for example whenever I'd die and restart the level, the death flag would still be active so I'd immediately die again. But overall this was a fun game with a ton of promise, and I enjoyed my time with it!
By the way, we played your game on our stream last night!
