Hello! We're glad you liked the prototype and thank you for your constructive feedback! ^^
The truth is, the enemies were designed not to be a threat but more of a slowdown (at least, in the prototype), because the gameplay is supposed to be relaxing action.
However, we would appreciate if you followed our game and share feedback like this in Coastal Goo's community threads to help the game grow in future releases ^^.
Thank you for your time!
