Well, technically, screen is not needed for a game at all. Rules and gameplay may be implemented in sound only. Any game designer up for a challenge? :)
First game I gave 5 stars. Of cause, there are faults (like, having to reset build and position each time killed in survival), but there are also so many little sweet things that counter that.
PS. KABOOM!
If head is near edge of screen, when turns to skull, you can hitlock it there and remove most oh it's health.
Also, use tombstones to accu,ulate exp and (I think) sp.
