This is a very interesting gameplay mechanic where you start off as a single heart block growing into a colossal killing spaceship! The overall progression in this game feels like I am playing vampire survivor! The gameplay didn't grow stale from throwing in bigger, faster, and tougher groups of enemies and to add another layer of complexity is to have the same weapon blocks attached to each other to make those weapons stronger to fight with. While it may not have any music and sound in the game, The controls are simple, the gameplays really intuitive & overall it's an impressively fun survival shooter game! Well Done!
