A great game, but it really, really needs a save feature! Also a level indicator and rooms on the map should change color once creeps have been killed.
I thought that the retro feel was great, but I'm not sure that is enough to carry a game. Controls were very responsive, something that's been lacking in a lot new games lately.
I want to like this game but: Controls are too loose and unresponsive. Mouse use should be available on all levels. Target ball should be a different color that target balls.
did you already kill 4 officers, one being level 4? did you skip lvl 3? zoom out an look at the big map, the green ones are cleared.
