You didn't need to distinguish between the good and the bad babies(cause I was planning to kill both hehehe), but it wasn't hard to distinguish which is which just from the colour scheme. But it would be better if you had provided an explanation. Also, https://prnt.sc/sx6tk0... And I did notice some ships being able to go beyond the given play area(just for a moment) and then snap back into place.
The game is a pretty solid shooter with amazing music if the mentioned bugs are fixed.
