I've torn between Robz Rush and Raiders Rush but I decided to choose the latter.
This game is actually my submission to Boss Rush jam which as the name implies, is a boss rush game. I choose this cause it has better boss select system which allows player to choose which boss to fight. Both games are boss rush games and both have upgrade features but this one has exchange system + hidden challenges.
The thumbnail only features two Raiders but the game has 4 Raiders to play as, each with his own specials.
