Very cool game :D! I noticed 4 things that would improve gameplay.
1. Add A System to regain health. You could use gelatin as a source.
2. Enhance visuals wiht UI, Particle Effects, and more sprites. the art style is good!
3. Add a reward for beating each level(e.g coins, more starting blobs, upgrades etc)
4. Add a lobby between levels for the player to organise their acquired items and stuff.
But the core gameplay is really good! Love the name!
