I feel bad reviewing this because I actually have no clue what the whole Drake and Kendrick beef is (sorry I live under a rock) but nevertheless, while I might not understand all the references, I can appreciate the humor and effort put into the game: there's just so much to play around with like different backgrounds, music, and characters all with their own animations, and there's a lot of charming touches like how if you idle, Drake gets a chance to sneak in a cheeky attack. That's quite impressive that the game is so neat despite me not understanding anything! Also this game just really feels like classic Newgrounds Assassin material: topical humor and beating up celebs never gets old!
I gotta admit though, that once you look past all of that (which again is very easy for me to do because I'm not familiar with the source material) the game just feels very shallow and is kind of style-over-substance. While most clicker games have an addicting sense of progression to them with all sorts of unlocks, the unlocks in this game barely feel noticeable and don't feel to be leading anywhere: once you play the game for a few seconds, you've pretty much seen everything it has to offer. In a way, maybe the game is too generous, giving you all the fun toys right from the start: I feel a bit silly holding that against it, haha!
You should get bonus points if you slap him to the beat, and especially to the wop!
