Wow you're right, the last level was quite the spectacle. Very bullet hell, but the previous level were really fun too. Took me a second to adjust my strategy since I chose Diagnosis at first, but once I figured out the trick, Diagnosis absolutely destroyed. Then in the last level I chose Addiction, which stacked really well with it.
Interesting concept and nice take on the theme. The way you portrayed the player health was a standout detail too. I also liked how each "word" choice actually changed how I approached the fights. Really cool entry. Glad I played through to the end.
