Thanks for the feedback!
Hmm, that sounds like a bug, there are definitely meant to be enemies! I am aware of the bug which causes the player to respawn at the start of each level, and sometimes that means the player spawns right on an already active bullet :( is it possible that happened? (but even then the enemies should keep spawning after your death, so maybe you found another bug)
Haha making the death sounds was fun haha, glad you enjoyed them haha. I will definitely rate yours too and leave feedback.
