This is a neat concept! It could use improvements in polish and gameplay, so here's a couple of things I noticed:
1. It feels frustrating when you hit a glob into another one, just to have it spawn a third. Even if I killed it in that hit, it doesn't feel like I made progress in the level. Maybe you could have code that identifies the reason a glob hit another (for example, did they run into each other, or did the player hit them into each other).
2. A follow up to thing 1 is that once the globs started coming together, I felt powerless to clear them because of the damage I do and the cooldown on my attack. There's probably some space to explore beyond tweaking numbers.
3. I wished this had felt a bit more chaotic, but because the enemies spawn in the same places it felt more like a puzzle-combat game rather than a "oh no, I gotta run for my life" every time I restarted a level.
Overall, I think this idea has potential and looking into the changes mentioned could be a good starting point for fleshing this out into a full game if you wanted. Congrats on submitting!
