Pretty cool! Getting into a rhythm was fun and satisfying, especially knowing exactly when my attacks are since I got to choose when they come! I would say the heal is a bit too powerful, since it's basically required to stay alive long enough. Adding damage indicators and invincibility frames would help a lot as well. Also the bomb insta-killing you could probably be reworked, especially since there's so much going on in later waves, making it difficult to notice where you launched your bomb each time. But regardless, I still had a fun time! Congrats on your submission!
