Great interpretation of the theme and quite a fun concept that is a fun take on the reverse wave and normal wave concept to play the enemy that actually want to help the hero and while i do like the sprites the lack of creative or interesting background isn't great but I love the gameplay. On the gameplay side maybe some kind of more descriptive or helpful UI to aide on understanding the gameplay mechanics could go a long way for such a unique gameplay since i was unfamiliar with the type of game and how that threat level number works on the start wave button
