The controls felt good. The Graphics on the first level where clear . And the Page you have set up here looks like too. Sound design was fitting for the era you are envoking.
I do feel that having space as menu control was a bit pointless. You could of stuck with K working as the A button and L as the B button. If the SpaceBar paused the game, that would of been ok, but there was no pause option as such space was only used in the menus. The Exit button the main menu didnt do anything too, I guess this is for exiting the game if running on desktop?
I also feel that if you the movement keys just selected the next "thing" on the menus rather then having a pseudo mouse cursor would also have felt better to play.
The MAIN take away is that I did have fun in the game itself. Menus aside you have a nice little cracker of a game here.
