Fun game! One thing I would recommend adding is a some sort of indicator when an enemy is about to shoot/attack, but overall it's a creative idea that's very well executed. Good job!
We tried to get that with the saturation of the blobs. When they're fully coloured they are able to attack, then go desaturated. We didn't have a chance to explain that mechanic so it's a little confusing. Thanks for playing and enjoying~!
