This is a fun concept. I found the strategy quite interesting: generally it seemed best to simply dodge rather than shooting, because the reward wasn't enough to justify shooting, but if you line up multiple enemies at once then it becomes worth it. My best time was 112 seconds. There were a few small things I think could be improved such as fireballs not hitting overlapping enemies, the hitboxes being slightly too big, and the worms being a bit too difficult to escape, but overall it was quite fun. Great work!
