Idk how much of a splash Heat SIgnature made but it's an incredibly slick 2d action game where you have to infiltrate space ships to do missions, and you have a lot of ways to do that. Like "Slow time throw a wrench at a guy's head steal his gun teleport across the room" ninja action stuff, or wacky hijinks with telport traps, some turret hacking. Basically it gives you a set of toys, like a big wrench, or a teleporter that will port you back to where you started after three seconds, or a shot gun, then says "Go figure out how to use these toys to achieve your goal" in procedurally generated space ships. I cannot overstate how well it takes a straightforward premise and executes it in an extremely satisfying way.
