The dialogue is fun and quirky, though uncomfortably stereotyped at times, and some of it paints an interesting story. Artwork, SFX, and music are all spot on.
The gameplay seems repetitive at first but introduced higher health enemies and new enemy types while gradually increasing the intensity of the waves does manage to keep things very fresh and enjoyable. One thing that strikes me as off for game-balance purposes is that Jr. is in a far more disadvantageous position compared to the other two characters, having to fend off two sides that are shorter distance at once while his parents only have to fend off a single long-distance path to them. It's rather telling that Jr. was the one I had to panic the most about, and how it was ultimately Jr. getting hit three times that ended the game while the parents I didn't have to stress about. You have a fun game but there's a stand-out weak link in keeping a fair balance in difficulty for the player.
I want to wish all fellow game developers and artists good luck in the Construct 3 Game Jam!
