This game is laced with fent. Despite it's extreme simplicity and potentially ugly outward appearance after one hit you are HOOKED. I've gotten 100 hours on both phone and PC and got 100% completion in less than a month. Fun weapons, great music, absurd humor, and so many secrets you can organically stumble across.

Also somehow beats PvZ as the game with the most insane and funniest bestiary. (It's that good I had to mention it)
