Lovely game, certainly immersive and rather addictive, lol, the F key felt a bit weird at first but got used to it I guess, also I just realized I could've used dash...
Protecting all eggs seems impossible, so I just focused on one and it felt like it could be possible to just go on forever, until you get bored, so maybe enemy speed could increase as score increases? Or their resistance to the boomerang? Also not sure if diagonal movement is normalized, it seemed like I could move slightly faster diagonally as opposed to horizontally or vertically.
On dev side: I get this warning "The size and depth of game_surface and window don't match!"
